thanks Karina, does that mean the remainder of the months will continue as is right? rather than post the balance within the month that it was cancelled? Unless I've misunderstood.. also how does one "merge the two perspectively"?

Welcome! yes, there will be two RevArrs running “cancelling” each other - if you do not merge. If you do merge (as you should) you have option of doing it perspectively (from this point on) or retrospectively (beginning of times) and per ACS606 it should be a perspective merge. There is a checkbox for it during the merge process. you will end up with one (new) RevArr and two lines starting Apr 1 through Dec 31 (your example) zeroing each other out.

thanks, @Karina - seems like merging is a manual process? How can I identify a revenue arrangement created by the SO and link that to the revenue arrangement created by the RGA? Trying to provide a link between both revenue arrangements automatically so as soon as the second revenue arrangement has been created, I know the original revenue arrangement - ideally would want this on a saved search so I can sift out revenue arrangements that have a refund vs ones that don't?

@G - yes, merging is manual, and you have to know what you are merging. Usually a company determines a strategy around merging if this is an ongoing process; a simple script is also written on it. Usually, once again, it is based on ACS606 criteria - two contracts are considered the same contract if items purchased within 3 months for example etc. So then all transactions included within these 3 months (SOs and RetAuths) are included in this merge. Again, this is done because of the re-allocations. If you do not have rev allocations you do not need to worry about it.
