Invoice application to receipt between 2 operating units

Hi,

I would like to seek your advise on how to handle below scenario in an automated manner:

1.) AR Invoice is created in OU1 (Branch A)

2.) Customer pays in OU2. (Branch

It is not possible to apply  the invoice in OU2 since they are different OU.

Is there a way to auto-apply the invoice to the receipt? Or what is the best practice to handle this?

Thanks a lot in advance.
