CL_POWL_QUERY_Accessor=======CP program termination

Hi Experts,

We are getting lot of dumps in ST22 with runtime errors : DBIF_RTAB_SQL_ERROR

Exception is CX_SY_EXPIMP_DB_SQL_ERROR

Termination Program is CL_POWL_QUERY_Accessor=======CP.

when I check in the log it is showing that  the termination is occurred in ABAP Program CL_POWL_QUERY_Accessor====CP in 'SET_CACHED_SELCRIT' method.

This program is a standard SAP program with respect to POWL Configurations.

Can anyone please thorw some light on how to resolve this runtime error.

I tried to check relevant SAP notes but no luck.

Please suggest  how to proceed on this.

Thanks,

Raghav
