Dimensions on Depreciation Routine

Hi

Has anyone got any comments on the query below

If you have dimensions on a Fixed Asset, and also different Dimensions on the Depreciation Cost account, when you run the Depreciation routine, using a balance account, ie, a separate journal line for the GL, it actually places the FA dimensions onto both lines, and ignores any dimensions on the GL?

Is this a bug, or is there some logic behind it
