Generic extractor on MBEW table

Hello Experts

I am creating generic extractor on MBEW.Requirement is to have all the available fields in MBEW to BW.

Now I have few questions:-

1.How can we enable the DELTA in Generic extractor.I mean which fieldd and which DELTA mechanism(Calder day,Time stamp and Numeric pointer) has to be considered.

2.My approach is like this FULL load to DSO and then DELATA to CUBE

Will it work.Please clarify.
