You want to modify the file at the following path:iw-home/TeamSite/local/config/lib/content_center/customer_src/etc/conf/customer/ui_custom.xmlYou'll need to run a make_toolkit.ipl to apply the changes. Read up on that in the guide.In a nutshell, you'll have to find the ID of the menu you wish to edit, and then use an <iwov-insert-before> or <iwov-insert-after> node to specify where you want your new item, and then actually create an element within that node to specify the attributes of the item you're adding. Look up that node in the guide to find the right section.
Then what is the use of customer_src under /ApplicationContainer/ ?I am using TS 7.3.2.
