Diagnosis
The system derives the value of the source field &V2& from the mappingrule and the target selection. It uses the value for the sourceselection to read the source data. However, the resulting value '&V1&'exceeds the length of source field &V2&.

System Response
'&V1&' is invalid as a value for source field &V2&. The system cannotread the source data.

Procedure
Examine the source and target fields in the mapping rule. Check whetherthe InfoObject of source field &V2& is suitable. You may need to use adifferent InfoObject with a greater length.
