• Message class: STC_TM - Task List Manager Messages

• Message number: 281

• Message text: Task list &1 has changed; execution of run &2 denied

What causes this issue?

The task list run has been created based on a different task list
version.

System Response

The execution of the task list run is rejected by default to avoid data
loss.

How to fix this error?

Check the software level of your system. To avoid data loss, the task
list run should only be continued if the current software level equals
the software level when the task list run has been created. The software
may have changed e.g. by applying SAP notes or support packages in
between.
It is possible to continue the task list run execution. But then it is
very likely that the execution will lead to data loss because tasks are
missing in the old or new task list version or task implementations have
changed.
