• What is the cause and solution for SAP error message RM820 - Reference qty zero (Target confirmation of all operations not possible) ?

  The SAP error message RM820, which states "Reference qty zero (Target confirmation of all operations not possible)," typically occurs in the context of production order confirmations. This error indicates that the system is unable to confirm the operations for a production order because the reference quantity is zero. Here are the potential causes, solutions, and related information for this error:
  Causes:
  
  
  Zero Reference Quantity: The most common cause is that the reference quantity for the operation you are trying to confirm is set to zero. This can happen if the production order was created without a valid quantity or if the quantity was reduced to zero during the planning phase.
  
  
  Incorrect Order Status: The production order may be in a status that does not allow confirmations, such as "TECO" (Technically Completed) or "CLOSE".
  
  
  Missing or Incorrect Data: There may be missing or incorrect data in the production order or the routing that prevents the confirmation from being processed.
  
  
  Operation Not Released: The operation you are trying to confirm may not be released for confirmation.
  
  
  Solutions:
  
  
  Check Production Order: Review the production order to ensure that the reference quantity is set correctly. You can do this by navigating to the production order in SAP and checking the details.
  
  
  Adjust Reference Quantity: If the reference quantity is indeed zero, you may need to adjust the production order to set a valid quantity. This can be done by changing the order quantity or re-creating the order if necessary.
  
  
  Check Order Status: Ensure that the production order is in a status that allows confirmations. If the order is in a status like TECO or CLOSE, you may need to change the status back to a confirmable state.
  
  
  Review Routing and Operations: Check the routing and operations associated with the production order to ensure they are correctly defined and released for confirmation.
  
  
  Use Transaction Codes: You can use transaction codes like CO11N (Single Screen Entry of Confirmations) or CO15 (Order Confirmation) to confirm the order and check for any additional error messages.
