• What is the cause and solution for SAP error message MPE_OAN149 - End event element &1 in OAN &2, version &3 has a successor ?

  The SAP error message MPE_OAN149 indicates that there is an issue with the end event element in a process model within the SAP system. Specifically, it suggests that the end event element (identified by &1) in the operational area network (OAN) identified by &2 and version &3 has a successor, which is not allowed.
  Cause:
  The primary cause of this error is that in a process model, an end event should not have any successors. An end event signifies the conclusion of a process, and therefore, it should not lead to any further elements or events. If there is a successor linked to the end event, the system raises this error to indicate that the process model is incorrectly defined.
  Solution:
  To resolve this error, you need to check the process model and ensure that the end event does not have any successors. Here are the steps you can take:
  
  
  Open the Process Model: Access the process model in the SAP system where the error is occurring.
  
  
  Identify the End Event: Locate the end event element that is causing the error. This will be indicated by the identifier &1 in the error message.
  
  
  Check Successors: Review the connections or links from the end event to other elements in the process model. 
  
  
  Remove Successors: If you find any successors linked to the end event, you need to remove those connections. The end event should stand alone without any outgoing links.
  
  
  Validate the Model: After making the necessary changes, validate the process model to ensure that it complies with the required structure.
  
  
  Save Changes: Once validated, save the changes to the process model.
  
  
  Test the Process: If applicable, run a test of the process to ensure that it behaves as expected without any errors.
