• What is the cause and solution for SAP error message FKKINV660 - Invoicing unit contains source documents for multiple master agreements ?

  The SAP error message FKKINV660 indicates that the invoicing unit you are trying to process contains source documents that are associated with multiple master agreements. This situation typically arises in the context of contract accounting or invoicing processes where the system expects all source documents to be linked to a single master agreement for the invoicing unit.
  Cause:
  
  Multiple Master Agreements: The invoicing unit has source documents (like invoices, credit memos, etc.) that are linked to different master agreements. This can happen if the documents were created under different contracts or agreements.
  Incorrect Document Assignment: There may be a misconfiguration or incorrect assignment of documents to the invoicing unit, leading to the system detecting multiple agreements.
  Data Entry Errors: Manual errors during data entry or document creation can lead to documents being incorrectly associated with different agreements.
  
  Solution:
  
  Review Source Documents: Check the source documents associated with the invoicing unit. Identify which documents are linked to which master agreements.
  Consolidate Documents: If possible, consolidate the documents under a single master agreement. This may involve adjusting the documents or creating new ones that are correctly associated with the intended agreement.
  Adjust Invoicing Unit: If the invoicing unit is meant to handle multiple agreements, consider creating separate invoicing units for each master agreement to avoid this error.
  Correct Document Assignments: If there are errors in the assignment of documents, correct these in the system to ensure that all documents in the invoicing unit are linked to the same master agreement.
  Consult Documentation: Refer to SAP documentation or help resources for specific guidance on handling invoicing units and master agreements in your version of SAP.
