Diagnosis
The intervals for keys TypEKV = &V1& and ArtEKV = &V2& overlap.
Example:
TypEKV ArtEKV LowLimit UppLimit Months
0001 0001 25 60 1
0001 0001 55 70 2
In this example, the intervals [25,60] and [55,70] overlap. The systemcannot find a clear allocation to the number of months.

Procedure
Maintain the intervals so that they do not overlap.
