Anil,
Have you already checked yourself in system? Do this:
- Create a sales order with storage location X and save.
- If integration model is active for sales order for this material then you should see this sales order in /SAPAPO/RRP3.
- In RRP3 there is column sub-location which is nothing but storage location in sales order. You should see same i.e. X.
- Thereafter change Sloc to Y in VA02 for this sales order and save.
- Refresh RRP3 view and you should see Y in APO.
This is standard behavior until unless you have done some modification. Let us know if this resolved your issue. If yes, follow How to close a discussion and why
Regards
Rahul
