Hi Experts,
Looking for suggestions to handle below situation in PP/DS.
Initially the GR time for my in-house product was some value - say 2 days.
I have a number of process orders, spanning across months and is created with some backward scheduling strategies.
At this stage, the GR time is changed, to 3 days.
I am looking for some methods (preferable standard solutions) for the mass change of these orders availability date based on this new GR time.
I dont want any other thing to change (my start date/time, mode etc), except for the availability date .
My plan is to use "SAP_PP_021 - New explosion" with retain mode/operation time in forward scheduling mode; but I would like to know about the pros and cons of using this.
Or if there is any better method to achieve this, plz suggest that.
Heavy rewards waiting for useful answers
