I want to add a tab (sub-tab) to an already-existing tab. I found help here on this site for doing so, linking to the Epicor Customization User Guide. There, what I call tabs, they refer to as sheets, and I continued through the steps using Sheet Wizard. However, the New Custom Sheet needs a Dockable Sheet. For some reason, the sheet that I need to dock to is not in the list. How can I make it dockable so that I can proceed? Specifically, I’m working with the Customer Credit Manager screen. They have several dockable sheets, one being the Invoices tab, that has “All” and “UnappliedDepositInvoices” sub-tabs. I’d like to do something similar with the Orders tab, making an “All” underneath which does what the current Order tab does, as well as a “ShippedNotInvoiced” tab. So how can I get the current Orders tab (sheet) to be “dockable” and continue on my way through the user guide, or might there even be another way to accomplish this?
