  SAP Message W6012: Overview
  
  Message Text:
  
  Items posted (material document &)
  
  This warning typically appears during a goods movement or material posting transaction.
  
  
  Cause of W6012
  
  The message W6012 is a warning indicating that some items have already been posted in the system with a material document number (the placeholder "&" is replaced by the actual document number).
  This usually occurs when:
  
  You attempt to post a goods movement or material document that has already been posted.
  There is a duplicate posting attempt.
  The system detects that the material document exists and items have been processed.
  
  
  It can also appear if you try to reverse or change a document that has already been processed or partially processed.
  
  
  What does it mean?
  
  The system is informing you that the items you are trying to post are already posted.
  It is a warning, not an error, so the system allows you to continue but advises caution.
  This helps prevent duplicate postings which can cause inventory inconsistencies.
  
  
  Solution / How to handle W6012
  
  
  Check the material document number shown in the message:
  
  Use transaction MB03 (Display Material Document) to review the document.
  Verify if the document corresponds to the posting you intended.
  
  
  
  Verify if the posting is already done:
  
  If the document exists and is correct, no further posting is needed.
  If you intended to post a new movement, check your input data to avoid duplicates.
  
  
  
  If you want to reverse or correct the posting:
  
  Use transaction MBST (Cancel Material Document) to reverse the document.
  Then post the correct document.
  
  
  
  If the warning appears unexpectedly:
  
  Check for any batch jobs or background processes that might have posted the document.
  Coordinate with your team to avoid duplicate postings.
