how to load data from one Infocube to another request by request using DTP

Hi All,

I have a scenario where we are maintaining backup Infocube B for Infocube A. User loads data from a flat file many times a day in different requests. We need to maintain backup of the Infocube A on weekly basis. i.e data to be refreshed with delta update from cube A to cube B. There are some situations where user deletes some of the requests in Infocube A randomly after use. Will this change effect in back up cube B when performed data refresh from cube A to cube B. i.e. this functionality is similar to reconstruct in BW 3.5. Now we are running on BI 7.0 SP 9.

Can anyone answer this ASAP.

Many Thanks,

Ravi
