Thanks Rama..
1. Yes I am at DEV. Will update you my observation when I run the infopackage and check how much of time is taken for the load.
2. I agree and i have configured the same way already as you have mentioned. Only concern is for situations like:
If a user creates a billing doc today but gives yesterday date, then it will not be pulled as delta as the extraction for yesterday date has already taken place. is not it?
I am really worried about this. How can I model this situation ?
Many thanks to you as always-
Cheers Aparajit
