Lead column settings for user &1 have been saved

What causes this issue?

The settings for the lead columns have been saved successfully. They
will now be taken into account every time manual planning is restarted.

System Response

If you only leave the period or overview screen to go to the selection
screen, for example, to reselect the planning levels, then the next
time you enter the period or overview screen, the lead columns will
still have the old settings. The current settings can only be adopted
if you restart the entire transaction.

How to fix this error?

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.
