• Message text: Planning function will be undone

What causes this issue?

You have undone the changes to plan data, which were made in the
current planning session by the planning function executed last.

System Response

The plan data is available again with the values which it had before
the last execution of a planning function.
If you have changed data manually in a planning layout since the last
execution of a planning function, then the system proceeds in one of
the following ways:
If you have not executed any actions since the last execution of a
planning function, which result in a commit event (for example,
navigation to another object in the planning environment), then the
system regards the change as not complete and undoes the data change,
which was made before the manual change by a planning function.
If the commit event already occurred after the manual change, the
system deactivates the possibility to undo the changes of the planning
function executed last.
