SMSDlg

Activate the two checkboxes Knowledge base and Inventory at Required rights. This way, only these users will get the menu item. In the other case EVERY HelpDesk user in the client would have the menu item available!

Example:

Type Menu item
Dialog Main dialog
Designation SCCM data (can be chosen freely)
Class Name SMSDlg
Image can be left free
Position any number (specifies the position of the tab)
Pass parameter can be left free
