Query regarding Landed costs

Hi Team,

Can anyone let me know how the weighted average cost and DMAAIs effects in below scenario .We are using only Stand Alone landed costs.

Created the purhase order for 10 EA with Unit cost 100 $ and and received 10EA using P4312 . after receiving 10EA to stock 5 EA have sold to customer and sales updated.

Now only 5EA left in stock and  Landed cost of 10$ per unit is applied to the purchase order using stand alone landed costs.

Please let me know how the weighted avergae cost and DMAAIs will update in this scnario.

Thanks in Advance.
