• What is the cause and solution for SAP error message WRF_AT_GENERATE012 - Purchase order &1 blocked ?

  The SAP error message:
  WRF_AT_GENERATE012 Purchase order &1 blocked
  typically indicates that the purchase order (PO) referenced by &1 is currently blocked and cannot be processed further in the workflow or transaction you are attempting.
  
  Cause
  
  The purchase order is blocked in the system. This block can be due to various reasons such as:
  
  Manual block set by a user (e.g., for review or correction).
  Automatic block due to inconsistencies or errors detected during processing.
  Block due to release strategy not being completed or approved.
  Block due to payment or invoice verification issues.
  Block due to goods receipt or invoice receipt discrepancies.
  
  
  
  
  Solution
  
  
  Check the Block Status of the PO:
  
  Use transaction ME22N (Change Purchase Order) or ME23N (Display Purchase Order).
  Enter the PO number and check if the PO is blocked.
  Look for any block indicators such as:
  
  Delivery block
  Payment block
  Release block
  
  
  
  
  
  Check Release Strategy:
  
  If the PO is subject to a release strategy, verify if all required approvals have been completed.
  Use transaction ME28 (Release Purchase Order) to check and release the PO if you have authorization.
  
  
  
  Remove the Block:
  
  If the block is manual and you have authorization, remove the block in ME22N by clearing the block indicator.
  If the block is due to release strategy, complete the release process.
  If the block is due to invoice or payment issues, resolve those issues first.
  
  
  
  Check Workflow or Custom Logic:
  
  If the error occurs during a workflow or custom program, check if the PO block status is being checked and causing the error.
  Adjust the workflow or program logic if necessary.
  
  
  
  Consult with Purchasing or Finance Team:
  
  Sometimes blocks are intentional for audit or compliance reasons.
  Confirm with responsible departments before removing any blocks.
