• What is the cause and solution for SAP error message WAB198 - Partner Function is not allowd for source structure &1 ?

  The SAP error message WAB198, which states "Partner Function is not allowed for source structure &1," typically occurs in the context of partner determination in SAP, particularly when working with sales documents, purchasing documents, or other transactional data that involves partner functions.
  Cause:
  The error is usually caused by one of the following reasons:
  
  
  Incorrect Partner Function Configuration: The partner function you are trying to use is not configured for the specific source structure (e.g., sales order, purchase order) in the system. This could be due to missing entries in the partner determination procedure.
  
  
  Incompatible Partner Function: The partner function may not be compatible with the document type or the specific transaction you are working with. For example, certain partner functions may only be valid for specific sales document types.
  
  
  Missing Partner Determination Procedure: The partner determination procedure assigned to the document type may not include the partner function you are trying to use.

  To resolve the WAB198 error, you can take the following steps:

  Review Partner Determination Procedure:
