Thank you Nikolay,
I didn't installed VW22 jet, but I will now.
There are user fields in the def_rec. I can't find a way to edit them.
The workaround is to create a new database. Connect it to the devices by hand. Type in my additional data in the data tap. The devices table can have additional columns for that purpose. This workes for me.
This data is not displayed when I add a new text field to the dev_label symbol I use for the schematic drawing.
But I don't understand why.
Best
Francisco
