Thanks Sanjay,
Now can we come back and discuss -
I have already known about 1) "replication by object", 2) "replication by model". Now I wanted to find out what to do with 3) USMD_EDITION_REPLICATE. This is a ABAP program that can be batch scheduled to do replication. My question is that will all 3 function generate the same results if each of which deals with the data in same condition?
Regards,
