• What is the cause and solution for SAP error message BK171 - A document is always completely reversed. ?

  The SAP error message BK171 ("A document is always completely reversed") typically occurs when you attempt to reverse a financial document that cannot be partially reversed. This is a common scenario in SAP Financial Accounting (FI) when dealing with certain types of documents, such as invoices or journal entries.
  Cause:
  
  Document Type Restrictions: Some document types in SAP are designed to be reversed only in their entirety. For example, certain types of invoices or credit memos may not allow partial reversals.
  Document Status: The document you are trying to reverse may already be in a status that does not allow for partial reversals.
  Configuration Settings: The configuration settings in the SAP system may dictate that certain document types must be fully reversed.
  
  Solution:
  
  Full Reversal: If you encounter this error, you will need to reverse the entire document rather than attempting a partial reversal. Use the appropriate transaction code (e.g., FB08 for reversing a document) and ensure that you are reversing the complete document.
  Check Document Type: Review the document type and its settings in the configuration to understand if it allows for partial reversals. If necessary, consult with your SAP administrator or FI consultant to see if changes can be made to allow partial reversals for specific document types.
  Review Document Status: Ensure that the document you are trying to reverse is not in a status that prevents reversal. For example, if the document has already been cleared or settled, it may not be possible to reverse it.
  Consult Documentation: Refer to SAP documentation or help resources for specific guidance on the document types and their reversal capabilities.
  
  Related Information:
  
  Transaction Codes: Familiarize yourself with relevant transaction codes such as FB08 (Reverse Document), FBRA (Reset Cleared Items), and others that may be applicable to your situation.
  SAP Notes: Check SAP Notes for any known issues or updates related to document reversal processes.
  User Authorization: Ensure that you have the necessary authorizations to perform document reversals in the SAP system.
  
  If the issue persists after following these steps, it may be beneficial to consult with your SAP support team or a functional consultant who specializes in SAP FI for further assistance.
