Insert Revenue accounts to the AR Interface (12.1.3)

Hello all,

I am working on a customized program that will search for Modifier lines - within the AR interface - and add a Revenue account to these Modifier lines.

My question is: In case I insert an account, would the AutoAccouting override it, or in case AutoAccouting finds an accounting record (within the AR Interface) it won't override it?

Please advise.

Thanks,

Tomer.
