• What is the cause and solution for SAP error message MPE_OAN043 - No end event is defined for operation activity network &1 ?

  The SAP error message MPE_OAN043 indicates that there is no end event defined for an operation activity network in the system. This typically occurs in the context of project management or production planning where operations are defined in a network structure.
  Cause:
  The error is caused by the absence of an end event in the operation activity network. In SAP, an operation activity network is a sequence of activities that are linked together, and each network must have a defined start and end event to ensure that the flow of operations is correctly managed. If the end event is missing, the system cannot process the network correctly, leading to this error message.
  Solution:
  To resolve this error, you need to define an end event for the operation activity network. Here are the steps you can follow:
  
  
  Access the Network: Go to the transaction code CN21 (Create Network) or CN22 (Change Network) in SAP.
  
  
  Locate the Network: Enter the network number that is causing the error and access its details.
  
  
  Check Events: Look for the events associated with the network. You should see a list of start and end events.
  
  
  Define End Event:
  
  If there is no end event, you will need to create one. You can do this by selecting the option to add an event in the network structure.
  Ensure that the end event is properly linked to the last operation in the network.
  
  
  
  Save Changes: After defining the end event, save your changes.
  
  
  Recheck the Network: After saving, you can recheck the network to ensure that the end event is now defined.
  
  
  Related Information:
  
  Transaction Codes: Familiarize yourself with relevant transaction codes such as CN21, CN22, CN41 (Display Network), and CN43 (Display Network Overview).
  Documentation: Refer to SAP documentation or help files for detailed information on managing networks and events in SAP.
  User Roles: Ensure that you have the necessary permissions to make changes to networks and events in the system.
  Testing: After making changes, it is advisable to test the network to ensure that it functions as expected without any further errors.
