I am trying to call a stored Procedure form JDBC Adapter 6.0.1 and I am returned:

com.wm.pkg.art.error.DetailedServiceException: [ART.117.4002] Adapter Runtime (Adapter Service): Unable to invoke adapter service AodsJdbc.DatabaseServices.osqwautg.StoredProcedures:sp_PivotHistoryReadings.

Can anyone tell me what this error means?

(I have a simple stroed procedure that works fine… same server same database, different tables)

Thanks
