RMA Type & RG Register Updation

Hi,

There are 4 RMA types available in case of RMA receipts in R12 - 173L, GOODS RETURN, PRODUCTION INPUT, SCRAP. I want to know effect on RG register for each of these RMA type.

I checked latest user guide(R12.2). This user guide specifies RG register effect in case of return type - Production Input, Return under 173L, Scrapped & FG Return. But, in R12, there is no 'FG Return', instead 'GOODS RETURN' is there. Besides this, as per this user guide, no RG register update will be made in case of 'FG Return'. But, in our instance, if we select 'GOODS RETURN' as return type, system is updating RG register.
