Hi,
1)Repair full request: as we know without disturbing deltas we go for repair full load.
so my question is if we do repair full load from which tables (setup tables or delta queue) data will come .if it is setup tables then why we go to repair full load as we have full load option right?
Actually repair full request concept was useful until BW 3.x only.Reason why repair full request.Earlier in DSO full load was not possible after delta loads so if you miss some data by chance then we used to go for repair full to fill those particular records from setup tables.
Check this thread about the same.

3)Data source: if we want replicate only one data source then what we have to do.
can we do it with t-code RSDS
You can replicate it with the tcode you mentioned else you might try with this function module
RSAOS_METADATA_UPLOAD
Give the logical system name and oltp datasource name which you need to replicate.
Hope this helps.
Regards,
AL
