Hi Rupesh,
Thanks for the response.
We are looking for a mass change option since we have a big number of orders to change; changing the individual orders in rrp3 wont work (users are always lazy) .
As given in the initial post, we have found SAP_PP_021 to be useful and the plan is to run variable heuristics in RRP3 for this with retain operations date and mode; in forward scheduling mode.
Idea is that i only want the availability date of these orders changed based on GR time changes, and nothing else (not the starting date/mode etc).
We tested it and it seems to be ok, but we are going to propose this to the users to use in production.
Thought of getting some expert advice before doing so, and to check if there are any better solutions to this (other than custom developments).
