Inventory Goods Receipt on moving average

Dear all,

I would like to know what should be done to always receive items on the current moving average price on the transaction Inventory Goods Receipt

Currently, the system let the user choose a price list, but none of them is the average price.

I tried the Last evaluated price, but the value is not always the same than the moving average.

Logistic people will use this transaction, and they should not have any choice, and moreover, I don't want them to see his information.

Any idea ?

thank you

Sébastien
