  SAP Error Message:
  WPOC006 - Goods receipts already exist for purchase order &, item &
  
  Cause:
  This error occurs when you try to perform a goods receipt (GR) for a purchase order (PO) item for which a goods receipt has already been posted. In other words, the system detects that the PO item has already been received (fully or partially), and the current transaction attempts to post a duplicate or conflicting goods receipt.
  Common scenarios causing this error include:
  
  Attempting to post a second goods receipt for a PO item that is already fully received.
  Trying to post a goods receipt with incorrect quantities or duplicate document numbers.
  Posting a goods receipt for a PO item that has been closed or blocked after the initial receipt.
  Data inconsistencies or incorrect reference in the transaction.
  
  
  Solution:
  To resolve this error, consider the following steps:
  
  
  Check the PO History:
  
  Go to transaction ME23N (Display Purchase Order).
  Enter the PO number and navigate to the Purchase Order History tab.
  Verify if a goods receipt has already been posted for the item in question.
  Check the quantity received vs. ordered quantity.
  
  
  
  Verify Quantities:
  
  If the PO item is fully received, no further goods receipt can be posted.
  If partial receipt was done, ensure the new goods receipt quantity does not exceed the remaining open quantity.
  
  
  
  Check for Duplicate Document:
  
  Ensure you are not trying to post the same goods receipt document twice.
  Check the document number and posting date.
  
  
  
  Use Correct Transaction:
  
  Use MIGO or MB01 for posting goods receipts.
  Make sure you select the correct movement type and PO item.
  
  
  
  Check PO Item Status:
  
  If the PO item is closed or blocked, you cannot post further goods receipts.
  You may need to reopen the PO item or create a new PO.
  
  
  
  Consult with MM/Inventory Team:
  
  If the issue persists, check with the Materials Management or Inventory team for any custom validations or user exits that might block duplicate postings.
  
  
  
  Technical Check:
  
  If you suspect a system inconsistency, check for any database locks or inconsistencies.
  Run transaction MB51 or MB03 to review material documents related to the PO.
