  Solution:
  
  Check Object Changes: Review the changes made to the object associated with the task list. Ensure that the changes are valid and that they do not conflict with the task list data.
  Reassign Task List: If the task list is no longer valid for the changed object, consider reassigning it to the correct object or creating a new task list that reflects the current state of the object.
  Review Task List Configuration: Ensure that the task list is correctly configured and that all necessary data is up to date. This includes checking for any missing or incorrect entries in the task list.
  Consult Change Logs: Use transaction codes like IW32 (Change Order) or IW33 (Display Order) to check the change logs for the object and see what modifications have been made.
