Hello,
>>By the way, there is no response I am expecting in step 1 and 3 while calling corresponding procedures. Only fetch records in step 2 gets the records using select statement with join.
That's the reason i was suggesting u to use everything in DB instead of making multiple calls.
>>There is a standard architecture they are following where in the consumer of the database (in this case PO 7.4) has to follow the calls in the sequence step 1, step 2 and 3.
IMO, u can certainly challenge the architecture if u are finding gaps in that.
BTW, if u are really interested in implementing this using NW BPM then u can post ur doubts here. Will try to help u in implementing the same.
Thanks
