How To Fix CRM_BRF043 - Multi-instance-logic deactivated for multi-instance tag

SAP Error Message - Details

• Message type: E = Error

• Message class: CRM_BRF -

• Message number: 043

• Message text: Multi-instance-logic deactivated for multi-instance tag

What causes this issue?

You are using a tag (expresson) that returns several values. However,
multi-instance logic is not activated. Only the first value returned is
taken into account.

System Response

If you want to use multi-instance tags, you have to activate
multi-instance logic in Customizing, otherwise only the first value is
taken into account.
Example: Rule (if item.partner.partner function = '0001' then action)
The expression used here could possibly return several values if more
than one partner with the partner function 0001 exists in the item. If
you set the indicator <DS:DE.CRMT_MULTI_INSTANCE_ON>Multi-Instance Logic
On</> in Customizing, a rule instance is generated for each returned
partner. This means that is possible that a defined rule is carried out
for each partner. To use this functionality, you have to explicitly
activate this logic.

How to fix this error?

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.

• What is the cause and solution for SAP error message CRM_BRF043 - Multi-instance-logic deactivated for multi-instance tag ?

  The SAP error message CRM_BRF043 indicates that the multi-instance logic has been deactivated for a specific multi-instance tag in the Business Rule Framework (BRF). This error typically arises when the system is trying to process a rule that is expected to handle multiple instances of data, but the configuration does not allow for it.
  Cause:
  
  Configuration Issue: The multi-instance logic may not be properly configured in the BRF settings. This could be due to the tag being incorrectly set up or not activated.
  Business Rule Design: The business rule may have been designed without considering the need for multi-instance processing, leading to a mismatch between the expected and actual behavior.
  Versioning: If there are multiple versions of the rules or tags, it’s possible that the version being executed does not support multi-instance logic.
  
  Solution:
  
  
  Check Configuration: 
  
  Go to the BRF configuration and verify the settings for the multi-instance tag. Ensure that the multi-instance logic is activated for the relevant rules.
  Make sure that the tag is correctly defined and that the necessary parameters are set to allow for multi-instance processing.
  
  
  
  Review Business Rules:
  
  Analyze the business rules associated with the error. Ensure that they are designed to handle multiple instances of data.
  If necessary, modify the rules to accommodate multi-instance logic.
  
  
  
  Testing:
  
  After making changes, test the rules with sample data to ensure that the multi-instance logic is functioning as expected.
  Use transaction codes like BRF+ to simulate and debug the rules.
  
  
  
  Documentation and Support:
  
  Refer to SAP documentation for BRF to understand the requirements and configurations for multi-instance processing.
