How do I apply a partial credit to an invoice? B1

[wuanameruns]

SAP B1 environment  - Is it possible to manually apply a partial credit memo to an invoice? Example $100 invoice, $10 credit memo and apply the credit memo to the invoice leaving a $90 balance to be paid on the invoice... I have not received any money from the customer.

In the BP  <Account Balance> screen if I select <Internal Reconciliation> on the bottom right it only allows me to apply credit to invoice if it's an exact match. 
thanks

Hello. Were you able to find a solution to this? Seems like a poor design flaw, as not all credit are an exact match.
