How can I remove button: Accept Customer Payment from Sales Order
It sounds like someone renamed an action. My guess would be it’s the “Create Deposit” action since its on the SO, but you should be able to find the name through the form.
On the top right hand side of any SO you’ll see “list” “Search” “Customize”. Hover over the word Customize and select customize form. Once on that page you’ll see a ribbon. Go to Actions. You should be able to find the action/button label in that list which would lead you to the action’s/buttons name.
