Down Payment (Billing Plan) with batch valuation

Hi SAP Experts,

We have a requirement to combine Down Payment (Billing Plan) with material costs when creating Billing document.

We are following batch valuation, thus, we derive material costs upon PGI (based on DN).

We all know that DPs are processed with reference to Sales Order, while valuation types are determined from Delivery Note.

I've searched in the forums and so far the solution mentioned is to create or modify copy control (SAP note 726039 - allow partial quantity billing for partial billing) where we can indicate the necessary logic to make it happen.

I just want to if there are other solution from configuration that we can avail of to resolve this issue.

Thank you for your help.
