Working offline/online and checkin/checkout in Embedded Planning

Hi All -

I am working in BPC 10.1 Embedded Planning, and Analysis for Office 2.2.

We have requirement to have check-in & check-out and off line & on-line in Input Plan data workbook.

1. Check-In /out data. If user A is working (or check-in) on planning against Cost Center A, and then user B is not allowed to do the planning to same Cost Center A. If user A has finished on planning against Cost Center A (or Check-out), then user B is allowed to do the planning against Cost Center A.
2. On-Line/Off-line. User is able to do a planning when he is not connected to Network. User saves his work in local first, and then submit it when he's connected to Network.

Could I kindly please ask your help to advice and share what you have done to meet the requirement above? are they possible done in BPC 10.1 embedded planning & analysis for office ?

Many thanks, and appreciate your advice,

Cheers,
