• What is the cause and solution for SAP error message M8013 - Purchase order & already selected (please delete line) ?

  The SAP error message M8013 ("Purchase order & already selected (please delete line)") typically occurs in the context of materials management and purchasing when there is an attempt to process a purchase order (PO) that has already been selected for a particular operation, such as a goods receipt or invoice verification. This error indicates that the system has detected that the specified line item in the purchase order is already being processed or has been locked for some reason.
  Causes:
  
  Duplicate Selection: The line item in the purchase order has already been selected for processing in another transaction.
  Locked by Another User: Another user may have the purchase order line item locked for editing or processing.
  Incomplete Previous Transaction: A previous transaction involving the same purchase order line item may not have been completed, leaving it in a locked state.
  System Configuration Issues: There may be issues with the configuration of the purchasing module or the way the purchase order is set up.
  
  Solutions:
  
  
  Check for Duplicate Processing:
  
  Verify if the purchase order line item is already selected in another session or by another user. If so, wait for that transaction to complete or ask the user to release the lock.
  
  
  
  Delete the Line Item:
  
  If you are sure that the line item should not be processed, you can delete the line item from the transaction you are working on. Ensure that you have the necessary permissions to do this.
  
  
  
  Complete or Cancel Previous Transactions:
  
  If there is an incomplete transaction, complete or cancel it to release the lock on the purchase order line item.
  
  
  
  Check User Locks:

  Consult with IT Support:
