• What is the cause and solution for SAP error message /PM0/ABP_TM_MSG021 - Update call violates execution sequence ?

  The SAP error message /PM0/ABP_TM_MSG021 Update call violates execution sequence typically occurs in the context of the SAP Advanced Business Application Programming (ABAP) environment, particularly when dealing with transaction management or update calls. This error indicates that there is a violation of the expected sequence of operations in a transaction.
  Cause:
  
  Incorrect Transaction Sequence: The error often arises when an update call is made in an incorrect sequence. For example, if a commit work is executed before all necessary update calls are completed, it can lead to this error.
  Nested Transactions: If there are nested transactions and the inner transaction is not completed before the outer transaction is committed, it can trigger this error.
  Asynchronous Processing: If there are asynchronous processes involved, and the sequence of updates is not maintained, it can lead to this violation.
  Error Handling: If there are unhandled exceptions or errors in the transaction logic, it may disrupt the expected flow and lead to this error.
  
  Solution:
  
  Check Transaction Logic: Review the logic of your transaction to ensure that all update calls are made in the correct order. Ensure that you are not committing the transaction prematurely.
  Debugging: Use the SAP debugger to step through the code and identify where the sequence is being violated. Look for any conditional statements that might skip necessary update calls.
  Error Handling: Implement proper error handling to ensure that if an error occurs, the transaction is rolled back appropriately, and the sequence is maintained.
  Review Asynchronous Calls: If your process involves asynchronous calls, ensure that they are properly synchronized and that the sequence of operations is maintained.
  Consult Documentation: Refer to SAP documentation or notes related to transaction management and update calls for any specific guidelines or best practices.
  
  Related Information:
  
  SAP Notes: Check SAP Notes for any known issues or patches related to this error message. SAP frequently updates its knowledge base with solutions to common problems.
  Transaction Management: Familiarize yourself with SAP's transaction management concepts, including commit work, rollback work, and the use of update function modules.
  Performance Considerations: Ensure that your transaction logic is optimized for performance, as inefficient code can lead to unexpected behavior and errors.
