Hi kelly smith
Indeed, there are not to much stuff to do. The best way to valuate stocks in SAP is with Actual Costing / Material Ledger, and i think it gives an acceptable approach in costing.
From my point of view, Standard cost (without ML) is not real nor accepted in lot of countries and Variable Cost is a mess if you work with production.
I know the system dont give the information that all the companies need so its necessary to develop Z reports (im talking about 90% of the cases the report dont cover customer requirements). I know that write abap code with ML active is a bit complicated but not impossible if you have a strong understanding of the functionality.
My question is. what SCM KPI you are talking about, exist lots and with different points of views. I recommend you write a more specific question and explain why you think the variance between standard and actual cost is not transparent according to your expectations. Also an example of what KPI (with a formula) can give people here a better understanding of your requirement.
