• What is the cause and solution for SAP error message APS_CKE_PARSER104 - Deleting the field with alias &1 is incompatible. ?

  The SAP error message APS_CKE_PARSER104, which states "Deleting the field with alias &1 is incompatible," typically occurs in the context of data modeling or when working with ABAP programs, particularly when there are dependencies on fields that are being modified or deleted.
  Cause:
  
  Field Dependency: The field with the specified alias is being referenced in other parts of the program or data model. Deleting it would break these references, leading to inconsistencies.
  Data Model Changes: If you are working with a data model (like CDS views or InfoObjects), the field might be part of a structure or a view that other objects depend on.
  Incompatible Changes: The system detects that the deletion of the field would lead to incompatible changes in the data model or program logic.
  
  Solution:
  
  Check Dependencies: Before deleting the field, check where it is being used. You can use tools like the "Where-Used List" in the ABAP Workbench to find all references to the field.
  Modify Instead of Delete: If the field is still needed, consider modifying its properties instead of deleting it. For example, you could change its data type or make it optional.
  Update Related Objects: If you must delete the field, ensure that all related objects (like views, programs, or reports) are updated to remove references to the field.
  Consult Documentation: Review any documentation related to the data model or program to understand the implications of deleting the field.
  Testing: After making changes, thoroughly test the affected areas to ensure that everything functions correctly without the deleted field.
