Thanks it works I created a recursive function and used it for sub menu. Issue is resolved. Just in case if any one interested I used men_item.tag property to store acl_id. reasons are as follows. I also says thanks to Topwiz for dynamicMenu In future I will implement it also.

01 We have 2-3 languages and verticals so menu objects are more

02 in Report Menu We have situation like one permission is enough for group of reports like item list, item list 2 columns, item list 3 columns, Item list Group wise

The window has a property MenuID which is a reference to the currently assigned menu. You can use it in script like this:

Menu lm_menu, lm_item

String ls_itemname

lm_menu = this.MenuID

Menu items have an array property Item that you can loop through:

li_max = UpperBound(lm_menu.Item)

For li_idx = 1 To li_max

   lm_item = lm_menu.Item[li_idx]

   ls_itemname = lm_item.Classname()

Next

You can have a table that has the classname and text of all the menu items that need to be controlled. I would create tables for users, groups, group membership, and assignment of menu items to groups.
