You want to create management records for task lists in this change

this object type:

You want to allocate one or more task lists to an alternative date you
selected.

How to fix this error?

If you want to process object management records, first set both
indicators for the object type <ZH>task list</>.
If you want to define the indicators more precisely for the different
types of task list, choose the <ZH>Edit</> menu, function <ZH>Object
sub-types</> -> <ZH>Task list</>.
If it is not possible to change this change master, choose a different
change number which contains these indicators.

You cannot change the <LS>valid-from</> date in the change header for
task lists. For this reason, you cannot allocate task lists to an
alternative date.
