The rules engine can radically boost your productivity in the PIM by automating actions. As explained in this article, a rule enables you to automatically apply one or several actions to a specific list of products and product models. To set the targeted products, you have to define conditions (that are composed of fields and operators).

The rules are defined in a YML file that you can import in the PIM using a dedicated job profile or via the interface.

To guide you in the rules engine usage, read below and find out what you can use it for and how it works.

Name your rules

Each rule must have a unique code. It can also have a label per enabled PIM locale. This label will appear under Settings/Rules and be visible in your product form under your smart attributes. You can add the labels' settings anywhere in your rule. In the example below, it is placed at the end of the rule, and it adds labels for your American English and French locales. Here is the expected format:

camera_copy_name_to_model:
    priority: 0
    conditions:
        -   operator: AND
            value:
                -   field: family
                    operator: IN
                    value:
                        - camcorders
                -   field: camera_model_name
                    operator: EMPTY
    actions:
        -   type: copy
            from_field: name
            to_field: camera_model_name
    labels:
        en_US: 'Copy name to model'
        fr_FR: 'Copie nom vers modèle'

If you do not want to add labels to your rule, leave the labels settings with { }.

labels: {}

You can also search on your rule labels under Settings/Rules.

Define a status for your rules

Thanks to the status, you can define whether or not the rule must be automatically executed.   
A status can be defined with the enabled key. The rule cannot be executed from cronjob or manually when the value is false.   
In the rule import, this key is not mandatory. If it's not specified, the rule is enabled and set to true, by default.   
To define the rule status, please follow this format:

camera_copy_name_to_model:
    priority: 0
    enabled: true
    conditions:
        -   operator: AND
            value:
                -   field: family
                    operator: IN
                    value:
                        - camcorders
                -   field: camera_model_name
                    operator: EMPTY
    actions:
        -   type: copy
            from_field: name
            to_field: camera_model_name
    labels:
        en_US: 'Copy name to model'
        fr_FR: 'Copie nom vers modèle'
        

As of today, eight actions are available in the rules engine:

1. Copy
2. Add
3. Set
4. Remove
5. Concatenate
6. Clear
7. Calculate
8. Generate

What are these actions for? Let's discover it 😉

Copy

The Copy action enables you to copy an attribute value in another one.

The expected values are:

• from_field: the code of the attribute to be copied
• to_field: the attribute code where the value will be copied
• from_locale: the locale code of the value to be copied (optional)
• from_scope: the channel code of the value to be copied (optional)
• to_locale: the locale code where the value will be copied (optional)
• to_scope: the channel code where the value will be copied (optional)

It is possible to copy values from an attribute type to another attribute of the same type (for example: from a text attribute type to another text attribute type). There are some exceptions, mind you!

You can go even further. It is possible to copy attribute values in another attribute value field even if they are two different types of values. There are some exceptions, mind you! Take a look at the list below.

You can copy the given attribute to a selection of attribute types that we defined based on logical criteria:

You can copy the option code of a simple select attribute to:

• a reference entity single link attribute (the record must already exist)
• a text attribute
• a text area attribute

You can copy the option codes of a multi-select attribute to:

• a reference entity multiple links attribute (the records must already exist)
• a text attribute (a comma separates the codes)
• a text area attribute (a comma separates the codes)

You can copy the value of a text attribute to:

• a text area attribute
• a simple select attribute (the option code must already exist)
• a reference entity single link attribute (the record must already exist)
• a number attribute (the value must respect the number attribute validation parameters. Only decimal separators (comma ',' or period '.') are authorized; no thousand separator (neither period, nor comma, nor space) is permitted.)

You can copy the value of an identifier attribute to:

• a text attribute
• a text area attribute

You can copy the value of a date attribute to:

• a text attribute
• a text area attribute

You can copy the value of a measurement attribute to:

• a text attribute
• a text area attribute
• a number attribute

You can copy the value of a number attribute to:

• a text attribute
• a text area attribute
• a measurement attribute

You can copy the value of a price attribute to:

• a text attribute
• a text area attribute

You can copy the record code of a reference entity single link attribute to

• a text attribute
• a text area attribute
• a simple select attribute (the option code of the simple select attribute must already exist)

You can copy the record label of a reference entity single link attribute to

• a text attribute
• a text area attribute

You can copy the value of a text attribute in a reference entity to:

• a text attribute
• a text area attribute
• a simple select attribute (the option code of the simple select attribute must already exist)
• a reference entity single link attribute (the record must already exist)

You can copy the value of a number attribute in a reference entity to:

• a text attribute
• a text area attribute
• a measurement attribute

You can copy the value of a reference entity multiple links attribute to:

• a text attribute
• a textarea attribute
• a multi-select attribute (the option codes of the multi-select attribute must already exist)

You can copy the value of an asset collection to:

• another asset collection attribute

Specificity regarding simple select/multi-select attributes

In a list, an option is defined by a code and a label (the label is not mandatory). When the rule engine performs a copy action, it uses the option codes.

To copy values from a simple select attribute to another or from a multi-select attribute to another, every option you want to copy must already exist in the target attribute.

For instance, if you have two attributes: Attribute 1 and Attribute 2, both containing sizes.  
You want to copy the size filled in Attribute 1 to Attribute 2. Both have an option with code "S", but this option doesn't have the same label: in Attribute 1, the label is Small, whereas, in Attribute 2, it is S.  
When you perform a copy action on one or several products to copy this size, the option with code S will be copied from attribute 1 to attribute 2 in your product page, and the result will be:

• Attribute 1: Small
• Attribute 2: S

EXAMPLE

You have a value per channel and value per locale attribute called description. You can copy its content from the en_US locale and the print channel to the en_US locale and the e-commerce channel. The action will be defined as follows:

actions:
              - type: copy
                  from_field: description
                  from_locale: en_US
                  from_scope: print
                  to_field: description
                  to_locale: en_US
                  to_scope: ecommerce

Add

The Add action allows you to add values to a multi-select attribute or a reference entity multiple-link attribute. Also, it makes it possible to add a product to categories and groups.

The expected values are:

• field: the attribute code or property
• items: the value codes. It has to be an array of the items you need to add.
• locale: the locale code for which the value is assigned (optional)
• scope: the channel code for which the value is assigned (optional)

EXAMPLE

To add the “t-shirts” category to a set of products, the action will be as follows:

actions:
              - type: add
                  field: categories
                  items:
                    - t-shirts

Add associations

The add action can also associate products/product models/groups without removing previously associated ones. You can choose only to associate products or product models or groups, or any combination you like.

For instance, the following action will associate the product_42 product and the tshirt group to your product (while keeping previously associated products and groups), and won't update the associated product models.

actions:
              - type: add
                field: associations
                items:
                    X_SELL:
                        products:
                          - product_42
                        groups:
                          - tshirts

Set

The Set action assigns values to attributes and system properties: categories, status (enabled/disabled), groups, family, and associations. Beware, the new ones will replace the previous values.

The expected values are:

• field: the attribute code or property
• value: the attribute value or property value
• locale: the locale code for which the value is assigned (optional)
• scope: the channel code for which the value is assigned (optional)

EXAMPLE

To set the “My very new description for purple T-shirt” value to your description attribute in the en_US locale and for the e-commerce channel, the action will be as follows:

For instance, the following actions will disable the product and set its family to shoes. It will also categorize it in casual and women (while uncategorizing it from its previous categories), and add it to the summer group (while removing it from its previous groups).

actions:
              - type: set
                field: enabled
                value: false
              - type: set
                field: family
                value: shoes
              - type: set
                field: categories
                value:
                   - casual
                   - women
              - type: set
                field: groups
                value:
                  - summer

Set associations

As for the add action, you can associate any combination of products, product_models, or groups for each association type. You can decide which associated products, product_models, or groups you want to update. The other ones will not be updated.

In the example below, you can see that the following action will replace the associated products for the X_SELL association, but won't replace associated product models or groups.   
And for the UPSELL association, it will replace the associated product models and groups but not the associated products.

actions:
              - type: set
                field: associations
                value:
                    X_SELL:
                        products:
                          - product_42
                          - another_product
                    UPSELL:
                        product_models:
                          - amor
                        groups:
                          - tshirts

Remove

The Remove action enables you to remove values from a multi-select attribute, a reference entity multiple link attribute, an asset collection attribute, a price collection attribute, a product category or a group.

The expected values are:

• field: the attribute code or “categories”
• items: the value codes to remove
• locale: the locale code for which the value is assigned (optional)
• scope: the channel code for which the value is assigned (optional)
• include_children: if true, then it also applies the removal of the children to the given categories. It is only applicable if the field is set to “categories” (It's optional. By default, it is set to false)

EXAMPLE

To remove the “t-shirts” category, the action will be as follows:

actions:
              - type: remove
                  field: categories
                  items:
                    - t-shirts

To remove the “clothing” category and its children, the action will be as follows:

actions:
              - type: remove
                  field: categories
                  items:
                    - clothing
                  include_children: true

To declassify products from the whole “Master catalog” tree, the action will be as follows:

actions:
              - type: remove
                  field: categories
                  items:
                    - master
                  include_children: true
        

Concatenate

The Concatenate action concatenates at least two values into a single value. A space separates each source value.

The possible source attribute types are:

• Text
• Text area
• Date
• Identifier
• Measurement
• Number
• Price
• Simple select
• Multi-select (a comma separates values)
• Code from reference entity
• Label from reference entity
• Text attribute from reference entity
• Number attribute from reference entity
• Reference entity multiple links

The possible target attribute types are:

• Text
• Text area

The parameters from and to are required in this format. Depending on the source attribute type, some optional keys can be added.The expected values are:

from

• field: the attribute code.
• locale: the locale code for which the value is assigned (optional)
• scope: the channel code for which the value is assigned (optional)
• format: format of the date following the PHP format specification (optional, only relevant for date attributes). By default, it is Y-m-d (e.g.,i.e. 2020-01-31)
• currency: the currency code for which the price is assigned (optional, only relevant for price_collection attributes). By default, all the prices in the collection are displayed, separated by a comma.
• label_locale: the locale code for the label of the option or record (optional, only relevant for simple select, multi-select, reference entity single link, and reference entity multiple link attributes). By default, the code of the option is used.
• unit_label_locale: the locale code for the unit of the measurement (optional, only relevant for measurement attributes). By default, the code of the unit is used.

Here is an example:

actions:
            - type: concatenate
              from:
                  - field: brand
                  - field: color
                    label_locale: en_US
                  - field: name
                    scope: ecommerce
                    locale: en_US

to

• field: the attribute code.
• locale: the locale code for which the value is assigned (optional)
• scope: the channel code for which the value is assigned (optional)

EXAMPLE

To concatenate the brand (without a value per locale and without a value per channel) and the model in the en_US locale into the product title value in the en_US locale, the action will be as follows:

actions:
            - type: concatenate
              from:
                  - field: brand
                  - field: model
                    locale: en_US
              to:
                  field: product_title
                  locale: en_US

Clear

This action clears the value(s) assigned to an attribute, product category, product group, or product association.

The expected values are:

• field: the attribute code, "categories", "groups" or "associations".
• locale: the locale code for which the value is assigned (optional).
• scope: the channel code for which the value is assigned (optional).

EXAMPLES

To clear the brand in en_US locale, the action will be as follows:

actions:
            - type: clear
              field: brand
              locale: en_US

To clear all the categories that are linked to products, the action will be as follows:

actions:
            - type: clear
              field: categories
        

To clear all the product associations, the action will be as follows:

actions:
            - type: clear
              field: associations

Calculate

This action allows calculating numeric attribute values, with simple mathematical operations (addition, subtraction, multiplication, and division).

This action only accepts number, measurement or price collection attributes for both the source and the destination. Additionally, a number attribute from a Reference Entity can be used as the source only.

The action is split into 3 required steps, and 1 optional:

destination: the value you want to update. It is composed of:

• field: the attribute code (required)
• locale: locale code if the attribute is localizable (optional)
• scope: channel code if the attribute is scopable (optional)
• currency: currency code if the attribute is a price collection (required if the destination attribute type is a price collection)
• unit: unit code if the attribute is a measurement (optional, the default measurement unit of the attribute will be used if not set)

source: the first operand of the operation. It requires at least either a value or a field and additional items. For instance, you can have:

• value: a constant numeric value - decimal separator: dot, no thousands separator, e.g: 1515.14 (required)

OR:

• field: attribute code of the source value (required)
• locale: locale code if the attribute is localizable (optional)
• scope: channel code if the attribute is scopable (optional)
• currency: currency code if the attribute is a price collection (required if the source attribute type is a price collection)

operation_list: the list of operations to execute (at least one operation is required)

It is exactly the same format as the source property, with an additional required field:

• operator: can be either add, subtract, multiply, or divide (required)

If a product value required in an operation is empty or if a division by zero occurs, the product won't be updated.

round_precision (optional): rounds the final result of the operation(s)

If this parameter is not specified or if the value is null, the final result will not be rounded. The round precision can be:

• a positive number: it represents the number of decimals to keep
• 0: rounded with no decimal
• a negative number: the rounding will occur before the decimal point (for example, with a precision of -1: 81 becomes 80, with a precision of -2: 81 becomes 100)

If the destination attribute does not allow decimals, the action can be applied only when the result is an integer. This behavior can be changed by setting up the round_precision to 0: the result will be rounded, and the action will be applied.

EXAMPLES

For instance, to calculate the volume of a cone (volume = (π x R² x h) / 3), given a radius and a height, you can use the following action:

actions:
              - type: calculate
                destination:
                  field: volume
                  unit: CUBE_CENTIMETER
                source:
                  value: 3.14
                operation_list:
                  - operator: multiply
                    field: radius
                  - operator: multiply
                    field: radius
                  - operator: multiply
                    field: height
                  - operator: divide
                    value: 3

The following action will calculate a price in euros, based on the price in dollars and a ratio, and round the result to the nearest integer value:

actions:
              - type: calculate
                round_precision: 0
                destination:
                  field: price
                  scope: ecommerce
                  currency: EUR
                source:
                  field: price
                  scope: ecommerce
                  currency: USD
                operation_list:
                  - operator: multiply
                    field: ratio

Generate

Generate with AI

You can now automate content generation for a range of products using AI-Enhanced Enrichment, thanks to two new actions available in the Rule Engine: 

• 'Generate attribute value with AI’ 

• 'Generate translation with AI'

To use the two new rules, you will need first to enable AI for content generation and/or translation at the attribute level. 

On the tab ‘Generative AI’ of your attribute in Settings/Attributes, select ‘Yes’ if you want to enrich this attribute through AI. Then, select the attributes (text or text area attributes) that you would like to consider when generating product content within the attribute you enable with Generative AI.

Then, select a pre-defined template of instructions (’System prompt’) that will be used to prompt OpenAI’s ChatGPT and allow it to be as precise as possible in the content that will be created. You also have the option to generate a custom template of instructions (’System prompt’) if you choose ‘Custom’ in the drop-down list.

• How to set up these new rules?

You can define the ‘Conditions’ for your Product Selection in the first part. The attributes or system fields will select and filter your products/product models. Altogether, your Conditions will create your 'Product selection'.

To generate AI-Enhanced product content in the Rules Engine, select the action ‘Generate attribute value with AI’: you must select the target attribute where product content will be generated, and the channel and locale of your choice.

To generate AI-Enhanced product translation in the Rules Engine, select the action ‘Generate translation with AI’: you must select your source attribute with channel and locale and then your target locale(s). You can select one or several locales as your target.

To learn more about our AI-Enhanced enrichment feature and additional capabilities in the PIM, check out our dedicated article.

Generate Dynamic Content

This feature lets you dynamically insert product information into your dynamic templates, using the “Generate Dynamic Content” rule in the PIM. Imagine you want to create a product description that includes the product's name and color. To do this, you'll use the attribute codes assigned to these properties in your PIM.

Here's a basic example:

Let's say you have a product and want to include its name, stored in an attribute called product_name, and its color, stored in an attribute called product_color, in your description. You would write the following template:

This product is called {{ product.product_name }} and its color is {{ product.product_color }}.

When this template is processed, it will be replaced with the actual values from the product. For instance, if the product's name is "Elegant Lamp" and its color is "Golden", the output would be:

This product is called Elegant Lamp and its color is Golden.

Key Takeaway:

• Replace product_name and product_color in the example with the actual attribute codes from your PIM.
• The general format is {{ product.attributecode }} where attributecode is the code of the attribute you want to retrieve.
• The table below provides more detailed examples for various attribute types and advanced options.

Remember that the feature uses Twig, a powerful templating language. While basic usage is straightforward, you can refer to the provided Twig documentation for more complex operations.

Integrate product values in your dynamic content

Here is a table with most common ways to retrieve values from a product.

If you need more advanced information go the next section of this page. Keep in mind this a just a sum of common expressions but you may need to use most advanced Twig configurations depending on your needs.

Here is a list of attributes types & properties available : Text, Number, Measurement, Price, Simple Select, Reference entity single link, Family, Category

Preview your dynamic content

Before applying your rule to all target products, use the preview feature to verify that your content generates as expected.

Steps:

1. Enter your template: In the designated area, type or paste your dynamic content template.
2. Select a preview product: Click the "Preview Product" button and choose a specific product or product model from the list.
3. Review the results: The preview will display the generated content for up to 3 matching products and/or product models. For accurate results, especially with complex templates, it's recommended to initially shorten your product selection with a single, representative product.
4. Refresh the preview: After making changes to your template, click the refresh icon (arrows) in the top right corner to update the preview.

Note: Some dynamic content might be generated (and previewed) as empty in the following contexts:

• The attribute is empty for the product.
• There is a syntax error in the dynamic value (incorrect attribute code, invalid characters, etc.).

Available fields

Now that you have discovered all the available actions, you can easily see which can be useful in your daily work 😉. But, to write a rule, you must define your product selection. You need to know the available fields and their operators to do so.

As of today, the following fields are supported in the rules engine, and each of them has its own business rules. Here we go!

Created

The possible operators for the created field are:

• =
• ≠
• ‘>’
• <
• BETWEEN
• NOT BETWEEN
• EMPTY
• NOT EMPTY

EXAMPLE

A real example

You're done with all these specifications!

We hope that you perfectly understand the rules engine operation now. But to clarify it, we thought it would be better to take a real example of a rule 😉.

Let's say that, among all the attributes of your product form, you have one price collection attribute type and a boolean attribute type. In the price collection, you define the price of your product in USD. The boolean attribute defines if your product is ready to be sent to your ecommerce platform (if it is set to "yes", it means that the product is ready).

Manually changing the status of the boolean attribute is time-consuming and a very repetitive task... But for the rules engine, it's a perfect match! The mission of the rules engine here is to automate the status change of the boolean once the price attribute has a value.

To do so, follow these steps:

1. Open a text editor to write the YML code of the rule.
2. Write this:

my_rule:
    priority: 90
    enabled: true
    conditions:
        -   operator: AND
            value:
                -   field: basic_price
                    operator: NOT EMPTY
                    value:
                        amount: null
                        currency: EUR
    actions:
        -   field: ecommerce_ready
            value: true
            type: set
    labels:
        en_US: 'Set ecommerce_ready'
        fr_FR: 'Définir ecommerce_ready'

And finally, import your YML file using the Akeneo rules import job.

If you want to execute the rule directly:

1. Go to Settings, Rules
2. Click on the "play" button on your rule line and confirm.

The rule is executed 😉
