Diagnosis
For field &V2& of query &V1&, you have assigned the conversion exit &V3&that is not implemented in the current system.

System Response
Since the implementation of the conversion exit is missing, the systemis not able to perform conversions between the internal and the externalformat of the values of field &V2&. If the field is used as a queryinput field, the system always expects that you enter values in theinternal format. If the field is used as a query result field the systemalways displays values in the internal format.
