Nav 2016. Creating permission sets for different groups.

Does anyone know which table is effected when trying to expand Fast Tab sections. Ex: Sales Order, Lines section I’m trying to increase the number of lines I see on the screen. It’s not giving me any errors but doesn’t allow decreasing or increasing amount of info viewable.

There is no table for this as this is design and it is expandable . Check if page is non-editable

Yes this not at all any how related to Permission sets.

Just point your mouse to the bottom of that page(Sales Order Subform), there your mouse icon will get changed to different Icon which will allow you to expand it. There’s no where dependency of this.
