SAP ISU BP blocking

Hi There ,

There are 2 fields in BUT000 table i.e. XBLCK and NOT_RELEASED.

Anybody used any of the above fields to block central processes ?

Is this like if I set XBLCK field in BUT000 then no processes will be performed on that BP ?

If yes , can you help me with SPRO configuration for same ?

Thanks,

Manoj K
