Weighted average for Raw materials

Hi,

We have a question regarding cost method and manufacturing accounting.

Manufactured items Sales / Inventory Cost method = 07

For Purchased items Sales / Inventory Cost method = 02

If for a purchased item in P4105: 02=10, 07=8,

During manufacturing accounting R31802A while calculating IM cost for the purchased item which cost does the system considers 07 or 02?

Eg:

Raw material Cost  02 = 10, 07 = 8; work order quantity = 10

IM = 100 or IM = 80. Which is right as per JDE R31802A Calculations.

Regards,
