• What is the cause and solution for SAP error message CNV_PE_CHECK364 - Extension rule &1 will be used in both Selection and Enrich processes ?

  The SAP error message CNV_PE_CHECK364 indicates that there is a conflict in the use of an extension rule in the data migration process. Specifically, it states that the extension rule identified by &1 is being used in both the Selection and Enrich processes, which can lead to inconsistencies or unexpected behavior during the data migration.
  Cause:
  This error typically arises in the context of data migration projects, particularly when using SAP's Data Migration tools (like the SAP S/4HANA Migration Cockpit or other data transfer tools). The root causes can include:
  
  Duplicate Rule Usage: The same extension rule is defined for both the selection of data to be migrated and the enrichment of that data, which can create conflicts.
  Configuration Issues: There may be misconfigurations in the migration project settings or in the definition of the extension rules.
  Inconsistent Logic: The logic defined in the extension rule may not be compatible with both processes, leading to potential data integrity issues.
  
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Review Extension Rules: Check the extension rules defined in your migration project. Identify the rule referenced by &1 and determine where it is being used in both the Selection and Enrich processes.
  
  
  Modify Rule Usage: 
  
  If the same rule is not intended to be used in both processes, consider modifying the configuration to ensure that it is only applied in one of the processes.
  Alternatively, if the rule needs to be used in both processes, ensure that it is designed to handle the logic appropriately for both contexts.
  
  
  
  Test Changes: After making adjustments, test the migration process to ensure that the error is resolved and that data is being processed correctly.
  
  
  Consult Documentation: Refer to SAP documentation or guides related to the specific migration tool you are using for best practices on defining and using extension rules.
  
  
  Seek Support: If the issue persists, consider reaching out to SAP support or consulting with an SAP expert who can provide more tailored assistance based on your specific migration scenario.
