Config Parts , force to use * alternate for structure and routing

Hi,

(I am using IFS APP10 UPD10.)

Currently, I created 2 alterntes for one config parts.

(there is NO  Config-Alternates-Rule)

■Config Structure

　1) *

    2) ASSM

■Routing

　1) *

    2) ASSM

when I create a Shop Order,  I select “ASSM” alternate  for  both Strucute and Routing

While, After I “create configuration”,  then the  alternate changed to “*”

Is it a bug?

or is there any background logic behide?
