• What is the cause and solution for SAP error message RU521 - Only &1 &2 for previous operation &3 from order &4 has been confirmed ?

  The SAP error message RU521 indicates that there is an issue with the confirmation of operations in a production order. Specifically, it means that only a certain quantity of a previous operation has been confirmed, and the system is preventing further confirmations for the current operation until the previous operation is fully confirmed.
  Cause:
  The error typically arises in the following scenarios:
  
  Partial Confirmation: The previous operation in the production order has been partially confirmed, meaning that not all of the required quantity has been confirmed.
  Order Status: The production order may be in a status that does not allow further confirmations until the previous operation is fully completed.
  Dependencies: There may be dependencies between operations that require the previous operation to be fully confirmed before proceeding.
  
  Solution:
  To resolve the RU521 error, you can take the following steps:
  
  
  Check Previous Operation Confirmation:
  
  Go to the production order in question and check the confirmation status of the previous operation. Ensure that the required quantity has been confirmed.
  
  
  
  Complete Confirmation:
  
  If the previous operation is only partially confirmed, you will need to complete the confirmation for that operation. This can be done by:
  
  Navigating to the confirmation transaction (e.g., CO11N for single operation confirmation).
  Entering the necessary details and confirming the remaining quantity.
  
  
  
  
  
  Review Order Status:

  Check Dependencies:
  
  Review the routing and dependencies between operations. Ensure that all prerequisites for the current operation are met.
