the English description is misleading because it is not as accurate as the German
With this type of stock transfer, the transfer posting is not valuated at the valuation price of the material in the issuing plant, but is defined in both the issuing and receiving plants using conditions.
Bei dieser Art von Umlagerung wird die Umlagerung nicht zum Bewertungspreis des Materials im abgebenden Werk gebucht, sondern der Preis der Umlagerung wird sowohl im abgebenden als auch im empfangenden Werk über Konditionen definiert.
In German it just says "price" and is not talking about "valuation".
It only means that with this kind of stock transfer you have a purchase price in the receiving plant and a sales price in the sending plant which are both maintained as conditions.
The goods issue will of course be done at the valuation price in your material master, but you bill the other plant at a different price.
