R41815 didn't update cost in another branch plant

Hi All,

We want to change the inventory cost level from 2 to 3.

I simulate it first in PY910 with information as follows :

- Sales / Inventory Cost Method = 02

- Purchasing = 01

Cost Method	Branch Plant 11000	Branch Plant 11001	Branch Plant 11002
02	287.1555	305.5062	306.1163

When I run R41815, here's the processing option that I used :

Level - Inventory Cost = 3

Branch/Plant = 11001

Update Mode = 1

Print Mode = blank

The result is Inventory Cost Level change into 3, but the average cost appears in all Item Branch/Location/Lot combinations for B/P 11001 only (cost method 02 = 305.5062), while no cost (blank) formed in all Item Branch/Location/Lot combinations for B/P 11000 and B/P 11002.
