how to set up material valuation in MRP run (S/4HANA)

Hello,

We received a recommendation that talks about hot to set up material valuation in the MRP run, probably MRP live as it is about an S/4HANA implementation. This sounds to me as you could set up the MRP run in order revaluate materials. The only revaluation that I know is to either manually change the price on the material master or to cost material, mark and release the price. But I am not an expert in the MRP area.

Can anyone give me their insights please.

Thank you
