• What is the cause and solution for SAP error message MA391 - Assignments exist for event & - not possible to delete ?

  The SAP error message MA391 ("Assignments exist for event & - not possible to delete") typically occurs when you attempt to delete an event in the SAP system that has existing assignments or dependencies. This is common in modules like SAP Controlling (CO) or SAP Project System (PS), where events may be linked to various objects such as cost centers, internal orders, or projects.
  Cause:
  The error is triggered because the event you are trying to delete is still being referenced by other objects or transactions in the system. This could include:
  
  Open purchase orders or contracts linked to the event.
  Active projects or tasks that are associated with the event.
  Other master data or transactional data that relies on the event.
  
  Solution:
  To resolve this error, you need to identify and remove the dependencies or assignments associated with the event before you can delete it. Here are the steps you can take:
  
  
  Check Assignments: Use transaction codes like SE16 or SE11 to check the database tables related to the event. Look for tables that might hold references to the event, such as:
  
  COSS (CO Object: Cost Element)
  COEP (CO Object: Line Items)
  AFVC (Operation within an Order)
  PROJ (Project Definition)
  
  
  
  Remove Dependencies: Once you identify the assignments, you will need to either delete or modify them. This may involve:
  
  Deleting or closing any open purchase orders or contracts.
  Completing or archiving any projects or tasks linked to the event.
  Adjusting any master data that references the event.
  
  
  
  Use Transaction Codes: Depending on the context of the event, you may need to use specific transaction codes to manage the assignments:
  
  For project-related events, use CJ20N (Project Builder) to check project assignments.
  For controlling-related events, use KOB1 (Order Information System) to check cost assignments.
  
  
  
  Retry Deletion: After ensuring that all dependencies have been removed, attempt to delete the event again.
  
  
  Related Information:
  
  Documentation: Refer to SAP Help documentation for specific modules (e.g., CO, PS) to understand the implications of deleting events and the related data structures.
  SAP Notes: Check SAP Notes for any known issues or additional guidance related to the MA391 error.
  Consult with Colleagues: If you are unsure about the dependencies, consult with colleagues or your SAP support team to ensure that you do not inadvertently delete important data.
  
  By following these steps, you should be able to resolve the MA391 error and successfully delete the event in question.
