Diagnosis
In addition to the due date, you have also entered the from-date or theto-date.

System Response
The system differentiates between three selection types:

• Due date-related: you receive all the time-dependent data which is
valid for a specific due date.

• Period-related: you receive all data valid for a certain period. This
period may, however, be open either at the start or at the end.

• Without date: you receive all available data.

The system does not accept a combination of these selection types.

Procedure
Delete your due date and/or to-/from-date entry.
