Hi Jens,
Thanks again for the reply! Yes, I went through this path in spro. Indeed, it contains the majority of fields for a fleet object, but not the field "Variable Capacity" in DSD Vehicle Data tab. What I am thinking, is that because DSD is an add-on, maybe it is not defined a place from which you can set these fields as mandatory and what I need, is maybe an ABAP programmer to do this.
Best regards,
Eirirni
