• What is the cause and solution for SAP error message 40072 - Control key with external processing not possible for this operation ?

  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.
  
  
  Missing or Incorrect Settings: The settings for the control key in the configuration may be incomplete or incorrect, leading to this error when trying to process the operation.
  
  
  Solution:
  
  
  Check Control Key Assignment: Review the control key assigned to the operation in the production or maintenance order. Ensure that it is appropriate for the type of operation you are trying to perform.
  
  
  Modify Control Key Settings: If the control key is not suitable, you may need to change it to a control key that allows for the desired processing. This can be done in the routing or in the order itself.
  
  
  Review Order Type Configuration: Check the configuration of the order type to ensure that it allows for external processing. If necessary, consult with your SAP configuration team to adjust the settings.
  
  
  Consult Documentation: Refer to SAP documentation or help resources for specific details on the control key and its allowed operations. This can provide insights into what changes may be necessary.
  
  
  Testing: After making changes, test the operation again to ensure that the error is resolved.
  
  
  Related Information:
  
  
  Control Key Definition: Control keys in SAP define how operations are processed, including whether they are performed internally or externally, and they can also dictate other parameters such as costing and scheduling.
  
  
  Transaction Codes: You may use transaction codes like CO02 (Change Production Order) or IW32 (Change Maintenance Order) to review and modify the order details.
  
  
  SAP Notes: Check for any relevant SAP Notes that may address this specific error or provide additional guidance on control key configurations.
  
  
  User Roles and Authorizations: Ensure that you have the necessary authorizations to make changes to the order and control key settings.
  
  
  If the issue persists after following these steps, it may be beneficial to consult with your SAP support team or a functional consultant who specializes in production or maintenance processes.
