• What is the cause and solution for SAP error message STC_TM194 - Task '&1' can only be used once per task list, it is used &2 times ?

  The SAP error message STC_TM194 indicates that a specific task within a task list is being reused more than once, which is not allowed. Each task in a task list must be unique, and the error message specifies that the task '&1' is being used '&2' times, which exceeds the allowed limit of one usage.
  Cause:
  
  Duplicate Task Usage: The primary cause of this error is that the same task has been added multiple times to the same task list. SAP does not allow a task to be executed more than once in a single task list.
  Configuration Error: There may be a configuration issue where the task was unintentionally duplicated during the creation or modification of the task list.
  
  Solution:
  
  Review the Task List: Open the task list in question and check for the task that is mentioned in the error message. Look for any duplicate entries of that task.
  Remove Duplicates: If you find that the task is listed more than once, remove the duplicate entries so that the task appears only once in the task list.
  Save Changes: After making the necessary adjustments, save the task list and try to execute it again.
  Check Dependencies: Ensure that the task does not have dependencies that might require it to be executed multiple times in a different context. If necessary, consider restructuring the task list to accommodate the required logic without duplicating tasks.
