Valuation using cost estimate Vs. VPRS condition

Hi All,

I have a doubt and I hope someone can help me.

In my company we sell manufactured goods and trading goods, for manufactured goods we want to use Valuation using cost estimate, which works fine, but for trading goods I haven´t tried but it seems not to be right therefore, for trading goods (material type HAWA) I´m using condition VPRS for getting the COGS as a whole till here everything is fine but the problem is when I sell Finished goods, the system valuate my value field with condition VPRS instead of using cost estimate which I have customized. I thought it should be one way or another but not both, Any idea?

Thanks in advance,

Alejandro
