Planning Price 1 for SFG/FG from legacy system

Hi,

I have the Planning Price 1 field of SFG/FG populated with standard cost from legacy system

I have the following as the material valuation strategy in the standard costing variant

1. Planning Price 1

2. Standard Price

3. Moving average price.

My understanding is that the strategy is only for raw materials and purchased parts. I was wondering whether populating "Planning Price 1" field for SFG/FG would have any effect on their costing.

I would appreciate if someone could confirm on this.

Thanks for your help.
