  The SAP error message APS_CKE_PARSER125, which states "Adding the key field &1 is incompatible," typically occurs in the context of data modeling or when working with key fields in SAP applications, particularly in the context of Analytical Processing (AP) or data extraction processes.
  Cause:
  This error usually arises when there is an attempt to add a key field to a data structure (like a table or a data model) that is not compatible with the existing structure or configuration. The incompatibility can stem from several factors, including:

  Field Type Mismatch: The data type of the key field may not match the expected type in the target structure.
  Duplicate Key Fields: The key field being added may already exist in the data structure, leading to conflicts.
  Hierarchy Issues: If the data model involves hierarchies, adding a key field that disrupts the hierarchy can trigger this error.

  Remove Duplicates: Check if the key field already exists in the data structure. If it does, you may need to remove it or modify your approach.
  Review Hierarchies: If applicable, ensure that adding the key field does not disrupt any existing hierarchies in the data model.
  Consult Documentation: Refer to SAP documentation or help resources for specific guidelines on adding key fields in your context.
