I configured the toolbar access on the first screenshot:

• role: gardenadmin

• action: window

• window: sales order

• tab: sales orderline

• exclude Delete button

two problems (as shown in second screenshot)

• order tab is not showing delete button (although configuration is per tab)

• delete is being shown in line detail tab

( based on question triggered by Alex Yang https://groups.google.com/d/msg/idempiere/EfHFKTnuWDQ/sYLcdraYZkoJ )
