R31802A: Release 9.1, Std cost accounting (07), detailed by cost components G/L, IC F0911 A1 doesn't

Hi I was wondering if someone noticed same behavior in G/L transaction from R31802A when std cost is 07, Detailed Cost ="Y", Cost by WorkCenter is "Y".

Seems IC G/L transactions doesn't match F30026 of parent item

Ex.

Parent A F30026

A1 - 100

B1 - 50

C3 - 20

X2 - 10

---------

totale 180

WO 100EA completed without any scrap or discrepancy

G/L Transaction

IC - about A1 1050

IC - about B1  520

IC - about C2  220

IC - about X2  105

F4111 Transaction

IC - Qty 100, Paid 1800

Seems to me G/L transaction is based on components cost CSL+NetAdded of parents
