Smart SAP Assistant

• What is the cause and solution for SAP error message WSTI027 - Incorrect PDC inbounds exist. Post differences? ?

  The SAP error message WSTI027: Incorrect PDC inbounds exist. Post differences? typically occurs in the context of Process Integration (PI)/Process Orchestration (PO) or Central Finance (CFIN) scenarios, especially when dealing with Post Differences in the Post Document Change (PDC) inbound queues.
  
  Cause
  
  Incorrect or inconsistent PDC inbound queues exist in the system.
  The system detects that there are inbound PDC (Post Document Change) messages that are not correctly processed or are inconsistent with the expected state.
  This usually happens when there are differences in document postings that have not been reconciled or when the inbound queue contains messages that conflict with the current document state.
  It can also occur if there are duplicate or out-of-sequence PDC messages in the inbound queue.
  In Central Finance or system integration scenarios, this error indicates that the system is trying to post differences but finds that the inbound PDC messages are incorrect or incomplete.
  
  
  Solution
  
  
  Check the PDC inbound queue:
  
  Use transaction SMQ2 (Inbound Queue Monitor) to check the status of the inbound queues.
  Identify any stuck or erroneous PDC messages.
  
  
  
  Analyze the inbound PDC messages:
  
  Use transaction WE02 or SXMB_MONI (if using PI/PO) to analyze the inbound IDocs or messages.
  Look for inconsistencies or errors in the PDC messages.
  
  
  
  Reprocess or delete incorrect PDC messages:
  
  If messages are stuck or incorrect, try to reprocess them.
  If reprocessing is not possible, consider deleting the problematic messages from the queue after ensuring no data loss or inconsistency.
  
  
  
  Check document postings and differences:
  
  Verify the document postings in the source and target systems.
  Ensure that the differences that the PDC messages are supposed to post are valid and consistent.
  
  
  
  Synchronize document states:
  
  If there are inconsistencies, you may need to manually synchronize the document states between systems.
  This might involve manual correction or re-posting of documents.
  
  
  
  Apply SAP Notes or patches:
  
  Check for any SAP Notes related to WSTI027 or PDC inbound processing.
  Sometimes, SAP releases corrections for known issues causing this error.
