• What is the cause and solution for SAP error message APS_CKE_PARSER106 - Changing the CDS view of association &1 is incompatible. ?

  The SAP error message APS_CKE_PARSER106, which states "Changing the CDS view of association &1 is incompatible," typically occurs in the context of Core Data Services (CDS) views in SAP. This error indicates that there is an issue with modifying an association in a CDS view that is not compatible with the existing structure or usage of that view.
  Cause:
  
  Incompatible Changes: The error usually arises when you attempt to change an association in a way that conflicts with its current definition or usage in other CDS views or database objects. For example, changing the cardinality or the target entity of an association can lead to this error.
  Dependent Objects: If there are dependent objects (like other CDS views, analytical queries, or reports) that rely on the existing association, changing it can lead to inconsistencies.
  Semantic Errors: The change might violate the semantic rules of the CDS view, such as changing the data type or the nature of the association.
  
  Solution:
  
  Review Changes: Carefully review the changes you are trying to make to the association. Ensure that they are compatible with the existing structure and do not conflict with other dependent objects.
  Check Dependencies: Use the SAP tools to check for dependencies on the CDS view. You can use transaction codes like SE11 (Data Dictionary) or SE80 (Object Navigator) to find where the CDS view is used.
  Adjust Associations: If you need to change the association, consider creating a new CDS view instead of modifying the existing one. This way, you can maintain the integrity of the existing views while introducing the new logic.
  Activate All Dependent Objects: After making changes, ensure that all dependent objects are activated. Sometimes, the error can persist if there are unactivated changes in related objects.
  Consult Documentation: Refer to the SAP documentation for CDS views and associations to understand the implications of the changes you are making.
