We have a requirement of copying the shipment level DFF value to AR invoice DFF through AR invoice interface. We would like to derive the AR accounting based on the Value which comes from shipment level DFF.

Note: The EFF/DFF value will be concluded only during shipment creation, and we are not able to update the SO fulfillment line EFF at that point of time and also, we don't have an option to derive Dcogs/ COGS Accounting based on Sales Order Fline EFF.
