40072 - Details

• The SAP error message "40072 Control key with external processing not possible for this operation" typically occurs when there is an issue with the control key assigned to a particular operation in a production order or a maintenance order. This error indicates that the control key being used is not compatible with the type of processing that is being attempted.
  
  Cause:
  
  
  Control Key Configuration: The control key assigned to the operation may be configured for external processing, but the operation itself does not support it. This can happen if the control key is set up to indicate that the operation should be performed externally, but the system is trying to execute it internally or in a manner that is not allowed.
  
  
  Order Type Restrictions: Certain order types may have restrictions on the use of external processing. If the order type does not allow for external processing, you will encounter this error.
