Is there any way to customize the right-click context menu in NAV (2017). E.g. add an item to the list, so that the user can right click on, say an invoice or a customer, and choose an action (like run a codeunit or report). I'm pretty new to NAV and cannot think of a way to do it. I could of course just create a normal page action, but I'm curious if it's possible to do..
No you cannot edit the right-click menu options in NAV 2017. Neither in the Windows or web client.
