• What is the cause and solution for SAP error message CNV_OM_PRESEL136 - The following tasks and their successors have been selected for reset ?

  The SAP error message CNV_OM_PRESEL136 typically occurs in the context of the SAP Conversion or Migration process, particularly when using the SAP S/4HANA Migration Cockpit or similar tools. This error indicates that there are tasks that have been selected for a reset, but there may be issues with the dependencies or the state of those tasks.
  Cause:
  
  Task Dependencies: The error often arises when there are tasks that have successors or dependencies that are not in a state that allows for a reset. If a task has already been processed or if its successors are in a completed state, attempting to reset it can lead to this error.
  Inconsistent State: The tasks may be in an inconsistent state due to previous errors or interruptions during the migration process.
  Selection Issues: The tasks selected for reset may not be valid for the operation you are trying to perform.
  
  Solution:
  
  Check Task Status: Review the status of the tasks you are trying to reset. Ensure that they are in a state that allows for a reset (e.g., not completed or not in a state that prevents resetting).
  Review Dependencies: Look at the dependencies of the tasks. If there are successors that have already been processed, you may need to reset those tasks first or handle them appropriately before resetting the selected tasks.
  Use the Correct Functionality: Ensure that you are using the correct functionality for resetting tasks. Sometimes, there may be specific procedures or steps that need to be followed in the migration cockpit.
  Consult Documentation: Refer to the official SAP documentation or notes related to the migration process you are using. There may be specific guidelines or troubleshooting steps provided by SAP.
  Log Analysis: Check the logs for more detailed error messages or warnings that could provide additional context on why the reset operation is failing.
