RTP billing, how to get the device number in the billing doc?

Hi,

When billing a real device register with help of a load profile (RTP billing), we don't get the device number and the register id on the billing document lines created with the variant program QUANTI14.

Does anybody knwo why?

And is there a way to get those information in the billing document?

The goal is to be able to display of the print document the device registers and the corresponding quantities.

Thanks for your help.
