Stock Transfer, Between Plants

Dear friends,

MM guys are tramsfering finished goods from one profit center to another (plant to plant). in this case the price diffrence amount is posting to Dummy profit center but stock at actual cost is posting to currect profit center.

my question is why this dummy profit center is coming in to picture without assigning it to any g/l in obyc and i am not getting any idea in this.

troubling from 4 days... kindly solve my problem...

thank you
