&4 The scope item pointed to a deleted project and was removed

What causes this issue?

The planning scope or scenario scope of your scenario set contained
references to marketing projects that no longer exist.

System Response

The obsolete scope items were deleted from the scope.
The system will prompt you to save your data even though you may not
have made any changes yet. This is due to the fact that an inconsistent
state of your data has been automatically resolved. This is not an
error. As the marketing projects may be deleted outside the scenario
planner by other applications, and there is no online connection between
these applications at run-time, any changes can only be detected when
your scenario set is loaded in the scenario planner.

How to fix this error?

Save the data to keep the automatic correction.

Procedure for System Administrators
