Real-time valuation of actual data for COPA

Hi,

I see there is a point of valuation 01 for Real-time valuation of actual data in KEPC. I just wonder why do we need this real time valuation because COPA Cogs is posted from VPRS condition type. In this case why would anyone want to use point of valuation of 01 to revalue the VPRS cost.

I do understand the periodic revaluation makes more sense because we can revalue the COGS based on ML actual price. What i don't understand is the purpose of Real-time valuation of actual data.
