• What is the cause and solution for SAP error message WGDS_CONFIRMATION018 - Confirmation state rejected was rejected by the data pool ?

  SAP Error Message:
  
  WGDS_CONFIRMATION018: Confirmation state rejected was rejected by the data pool
  
  Cause
  This error occurs during the processing or posting of a goods movement confirmation (e.g., production order confirmation) when the confirmation status is set to "rejected" but the data pool (central confirmation system or integration layer) does not accept this status. The data pool acts as an intermediary or central repository for confirmations, and it enforces certain validation rules.
  Common causes include:
  
  The confirmation state "rejected" is not allowed or not expected by the data pool for the given confirmation type or process.
  The confirmation data sent to the data pool is inconsistent or incomplete.
  Configuration mismatch between the local SAP system and the data pool regarding allowed confirmation states.
  The data pool system is rejecting the confirmation due to business rules or validation errors.
  Network or communication issues causing incomplete or corrupted data transfer.
  
  
  Solution
  
  
  Check Confirmation Status and Process Flow:
  
  Verify if the confirmation status "rejected" is valid for the current process and confirmation type.
  Confirm that the rejection is intentional and correctly processed in the local SAP system.
  
  
  
  Review Data Pool Configuration:
  
  Check the integration settings between your SAP system and the data pool.
  Ensure that the data pool is configured to accept the "rejected" confirmation state.
  Consult with the team managing the data pool or middleware to verify allowed confirmation states.
  
  
  
  Validate Confirmation Data:
  
  Use transaction codes like COHV (Mass Processing of Confirmations) or CO11N (Single Confirmation) to review the confirmation data.
  Check for missing or inconsistent data fields that might cause rejection.
  
  
  
  Check Logs and Communication:
  
  Review application logs (SLG1) and communication logs (SMQ1/SMQ2 for queues, SXMB_MONI for PI/PO monitoring) to identify any errors or warnings during data transfer.
  Ensure that the data pool system is reachable and functioning properly.
  
  
  
  Correct or Reprocess Confirmation:
  
  If the rejection was due to incorrect data, correct the confirmation and repost.
  If the rejection was unintended, adjust the confirmation status accordingly.
  
  
  
  Consult SAP Notes and Support:
  
  Search for SAP Notes related to WGDS_CONFIRMATION018 for any known issues or patches.
  If the problem persists, raise a support ticket with SAP including detailed logs and system information.
