Hi Ashok,
First thing to clarify is RCJ_PS_PLAN is not a table, it is a structure. As you know structure can pull that data from different table.
With fields available in above sais table I could say it belongs to Network. With this field selection for the network can be made in below said path:
SPRO->IMG->PS->Structure->Operative Structure->Network->User Interface settings->Define field selection for Networks.
Regards,
Pradeep
