PS valuation material

Hi guru,

I have the following question about valuation of materials with PS ( project stock is used ).

When I produce a FG, the system posts costs of consumption and hours on the WBS element, and it is OK.

When I post good receipt of FG, I don't see the posting on WBS element. I read that "During the first goods receipt, the system saves a standard price in the individual stock segment for a material, plant and WBS element" from help, so my expectation is to have a standard price for the FG after the first good receipt but I don't have it

Please, could you help me to understand how can I have this standard price?

Thanks

Regards

Raffaele
