How can I keep AR and revenue separate in JDE as part of our business is sold but we are still going

Hello All JDE members,

I have question on AR module, here is my situation;

We have recently sold one of our office to a different company. But we will be doing their billing for them for the next several months.

I would like to understand how can I keep the revenue and AR separate, as that business doesn't belong to us anymore.

Your suggestions are highly appreciated.

Regards,

P
