SAP Message AQV137 - Functional area & should be regenerated (use Help)

Diagnosis
With Release 3.0C, access to database tables is optimized if possibleso that only the fields really required are offered when generatingquery reports. This considerably improves performance, but is onlypossible if the functional area contains information that permits suchan optimized access. This information is provided when the functionalarea is generated.
The present functional area was last generated for a release versionprior to 3.0C. Access to the database tables therefore cannot beoptimized.

Procedure
Have your system administrator generate the relevant functional areaagain. If you then generate the query report again, it might beprocessed much faster than in the past.
