Dear Chikkala Satish Kumar,
I think you might have aware about there are 3 client's in SAP.
1st Dev client
2nd Quality client
3rd Production
1st Dev client: Config part will be done & will be created TR's, So in your case whenever you are creating PA & PSA maintain with one TR. then those PA & PSA will be used at the time of hiring I mean whenever you are running personnel action by PA40 in initial screen info type 0000 PA will be used nest PSA will used in info type 0001. once you feel those testing is fine move that TR into quality then Production. Normally TR will be moved into quality & production by the BASIS consultant.
If still do you have any doubts kindly let us know...!!!!!!!!!!!!
Ur's
Mohan
