Diagnosis
The desired ranked list cannot be generated.
When you create a ranked list, lines are generated from the data undera particular event. This depends mostly on the ranked list criterion,but also on the key fields (non-numeric fields). The field reported asincorrect cannot be processed under this event, i.e. no meaningfulvalues can be determined for it. There are two different scenarioshere:

• The field is a non-numeric field.

In this case, the position of this field in the logical database iseither hierarchically lower than, or parallel to, the ranked listcriterion.

• The field is a numeric field.

In this case, the position of this field in the logical database iseither hierarchically higher than, or parallel to, the ranked listcriterion.

Procedure
Delete the incorrect field from the ranked list.
