• What is the cause and solution for SAP error message STC_TM202 - Task '&1' declares itself as successor ?

  The SAP error message STC_TM202 indicates that a task in the SAP Transport Management System (TMS) is incorrectly configured to declare itself as a successor. This typically occurs when there is a circular dependency in the task definitions, meaning that a task is set to follow itself, which is not allowed.
  Cause:
  
  Circular Dependency: The task is defined in such a way that it references itself as a successor, leading to a logical inconsistency.
  Configuration Error: There may be an error in the configuration of the task dependencies, where the task mistakenly lists itself as a successor.
  Manual Changes: If changes were made manually to the task definitions or dependencies, it could lead to this error.
  
  Solution:
  
  Check Task Definition: Review the task definition in the SAP system. Ensure that the task does not list itself as a successor. You can do this by navigating to the task in the TMS and checking its properties.
  Correct Dependencies: If you find that the task is incorrectly configured, modify the task to remove the self-reference. Ensure that the successor tasks are correctly defined.
  Transport Organizer: Use the Transport Organizer (transaction SE09 or SE10) to check for any inconsistencies in the transport requests and tasks.
  Recreate Task: If the issue persists, consider recreating the task from scratch to ensure that there are no hidden configuration issues.
  Consult Documentation: Refer to SAP documentation or notes related to TMS and task management for any specific guidelines or updates that may address this issue.
