Hello MN,
there is a standard transfer from cost centers to new GL.
Particularly for versions unequal to 0 it is used. (Refer to customizing of the newGL, please).
Make sure you activated the scenarion to transfer costs planned from CCA to newGL
(I guess it is FIN_CCA). Otherwise, the cost center number will not get transferred, only the profit center.
Hope it helps
Thomas
