Requirement dates not adjusted to new base date

What causes this issue?

You have changed the base date in the header data of the reservation.
The system proposed adjusting the <GL:date_required>"dates required"</>
in the reservation items to bring them in line with the new base date,
but you terminated the function.

System Response

The old requirement date in the reservation items will not be changed.

How to fix this error?

At this point you can:
leave the old "date required" shown in the reservation items unchanged,
change the base date again (the system will again propose an adjustment
of the requirement dates), or
change the "date required" in the individual reservation items manually
(in this case, choose the function "Goto -> Details from item...".

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