Interesting!

The AR batch shows only one detail.
After posting, the invoice posting journal shows only the entries for the total amount to the AR account & the AR clearing account. But there is now a cash posting journal for the payment amount, with a batch number, although the batch was never visible. The payment amount reduces AR and increases AR Bank Clearing.

So you cannot even show a payment and delete the cash batch to avoid duplication unless you require users to do retrievals.

When OE is used with Bank Rec, it would be nice to be able to show pre-payments made on invoices, without duplication. I'll try to work it out in optional fields.
