Enhancement Point for Copy Control Routines

Hi All,

I am creating a copy control routine(in Tcode VOFM) which is a copy of std routines 51 and 101 in Data Transfers->Sales Documents.My requirement is to combine these two routines and do some minor modification to the stds. I have copied the source code from the two routines but the routine 51 has enhancment points.

When I save the custom routine I am getting infomative message saying Enhancement point will be created for DATEN_KOPIEREN_051_10.Here i have to create a new enhancment spot and assign it to this.

Can't I use the same enhacment spot that std routine 51 was using. I tried doing this but i was getting an error messge.

Please suggest if there is a different way of doing this.

Thanks
