Activity price calculation with Material Ledger

Hello,

I'm almost ready to configure ML for a company activating on PRD system on May.

But I've still one doubt about activity price calculation.

In ACTIVATE ACTUAL COSTING  there are following entries:

2 Activity update relevant to price determination  and    1 Credit Cost Centers Using Alternative Valuation Run

Valuation run is running on CUMULATION  (YTD valuation) starting always from period 01

During previous months the company used following customizing for Activity price calculation

Do you think this customizing is correct and could work fine with ML customizing?

Thanks for your ideas and comments, they would be extremely useful for me.
