Locking data in BPS layout

Hi Guys,

I have one Planing Layout which different users will access for planning but for different Cost centers. But as of Now when User1 is loggining in it is fetching all Cost Centers and User2 is getting Locked . he is not able to change any plan data .

Now I want that when user1 will logon in BPS Layout ,he/she should fetch up the data for Cost centers for which he/she is authorized . So, other users should not be locked. they should continue to plan for other Cost centers.

your Suggessions will be hIghly Appreciated.

Thanks

Pankaj.
