• What is the cause and solution for SAP error message WG082 - Double PO found. Document &, item & will not be posted ?

  The SAP error message:
  WG082 Double PO found. Document &, item & will not be posted
  
  Cause:
  This error occurs during goods receipt or invoice verification processes when the system detects that the Purchase Order (PO) number and item combination already exists in the document flow or in the system for the same transaction. Essentially, the system identifies a duplicate PO item reference, which could mean:
  
  A goods receipt or invoice has already been posted for the same PO item.
  The document you are trying to post references a PO item that has already been processed.
  There might be a duplicate entry attempt for the same PO item in the current document.
  
  This is a safeguard to prevent double posting of goods receipts or invoices against the same PO item.
  
  Solution:
  
  
  Check Document Flow:
  
  Verify if a goods receipt or invoice has already been posted for the PO and item in question.
  Use transaction codes like ME23N (Display Purchase Order) and check the document flow to see if the PO item has already been processed.
  
  
  
  Review the Document You Are Posting:
  
  Ensure that the document (e.g., goods receipt or invoice) does not contain duplicate PO item lines.
  Remove or correct any duplicate PO item entries in the document.
  
  
  
  Check for Partial or Subsequent Deliveries:
  
  If partial deliveries or multiple invoices are expected, verify that the quantities and items are correctly referenced and not duplicated.
  
  
  
  Correct the Posting Document:
  
  If you find duplicates in the posting document, correct them before posting.
  If the document is correct and the error persists, check for inconsistencies or data corruption.
  
  
  
  Consult with SAP Support or Basis Team:
  
  If the issue is due to a system inconsistency or a bug, SAP support may provide a note or patch.
  Sometimes, database inconsistencies require correction via SAP support or database tools.
