Hi Gimmy,

You need to use the GetMasterItem method to get the master menu item of the application menu.

You can refer to the following link:

For your issue, you can use the following code example to test and see if it works:

RibbonApplicationButtonItem 				lr_AppButton
RibbonApplicationMenu 					lr_AppMenu
RibbonMenuItem 						lr_MenuItem
Integer 						li_Return, li_count, i 
string 							ls_tag, ls_text

ls_tag = "MyApp"  
li_Return = rbb_1.GetItemByTag (ls_tag, lr_AppButton)
li_Return = lr_AppButton.getmenu( lr_AppMenu)
li_count = lr_AppMenu.getmasteritemcount( )
for i = 1 to li_count	 
	li_Return = lr_AppMenu.GetMasterItem (i, lr_MenuItem)
	ls_text = lr_MenuItem.text
	ls_text = lr_MenuItem.tag	                         //Get the tag
	
	lr_MenuItem.text = ls_text + "1"			//change the text content	
	lr_AppMenu.setmasteritem( i, lr_MenuItem)		//reset the menuitem
next 

lr_AppButton.setmenu( lr_AppMenu)
rbb_1.setapplicationbutton( lr_AppButton)

BTW, The GetItemByTag and GetItem functions can be used to get items including ApplicationButton, TabButton, Category, Panel, Group, LargeButton, SmallButton, CheckBox, and ComboBox; but cannot get RibbonMenuItem, RibbonApplicationMenu, and RibbonMenu. To get RibbonMenuItem, you can use the GetItem, GetMasterItem, and GetRecentItem functions. To get RibbonApplicationMenu and RibbonMenu, you can use the GetMenu and GetMenuByButtonHandle functions.

You can refer to the following link for detail.
