Generic Delta on Texts

Hi All,

Here is what I wanna achieve. I want to do a delta on Masterdata Text. I'm using a DB View for generic extraction. When I try to do a Generic Delta, I see only 3 fields,MANDT, AUFNR and TXTMD.

Now my question is -

Can I do a delta on AUFNR?

If so, what kind of delta should i be using? (Time stamp, Calender day or Numeric Pointer)

And for the settings, would it be a New Status for changed records or Additive delta?

If the above isnt possible, how would I be able to achieve delta?

Thanks in Advance. Any help or pointer would be appreciated and fully rewarded.

Thanks,

Mav
