New requirement in Procurement process from 1st stage Dealer

Hi Xperts

In case of Dealer's Procurement scenario in India, we use the MRP-Indicator to change the Excise Base Value with Actual material value to have correct material valuation.

Now our requirement is to flow this Excise Base Value/Actual Material Value automatically while doing MIRO. Generally when we do MIRO against PO , system takes PO Net Price which we do not want for which we have to manually edit that value & we want this automated. we are using GR based IV as well.Pl advice
