Just received my new system and trying to add new products but I’m not able to add them because I can’t edit all the mandatory fields. I cannot figure out how to assign a printer group, exclusive tax or revenue center. On the tutorial video it shows an “assign” button next to them, I don’t have that on my screen. I know I have configured a printer group, and I tried to figure out where I would even add tax information with the user manual but I can’t figure it out. I’m using the touch screen keyboard, would it help if I got a real keyboard for the setup? Help would be appreciated
