So i have a sales order where it creates a R.A when its first created. However a few months down the line we are adding lines to the sales order ( which get added to the same R.A). What i am looking for is to be able to create a new R.A for these lines so that i can do a PERSPECTIVE MERGE (as thats what i am interested in ). I want to ensure the allocation runs on the perspective basis and not retroactive basis which it seems to be doing today by default. Any ideas?
