I created a customized version of Customer. It’s really small, just added a field box for information.
Now I am having difficulty setting it as the main/default view for this menu item. The customization is saved and I can view it in Customization Maintenance but when I go to select it for Customer in Menu Maintenance it isn’t there.
I would check to make sure the Company matches. You can’t set a module that has “All Companies” set with a customization that is owned by a company, and the same is true for a module owned by one company with customizations set to “All Companies”.
