Diagnosis
You chose a field for counting. You previously defined that temporaryvalues for counting should be output for the control level specified inthe warning, but this is not meaningful for a field used for countingon this control level. The control level field lies in the logicaldatabase in a segment that is hierarchically lower than the field usedfor counting.

Procedure
Check if the fields you selected, the sorting sequence and the fieldsfor counting really make sense.
