Hi D_Meethu,
I will reveal you how I would check the security. In this case finding the related privilege/duty using the security development tool is cumbersome as you are multiple levels deep in opening forms/menu items starting from the main menu.
The next steps will provide you the information which security objects are related.
1) When you are the system administrator, you can right click on the last shared form and choose the option 'Personalize'.
2) On the Personalization form, go to the Information tab and click 'Edit' behind the Form name.
3) The AOT opens. Now find the 'User default' button in the design or design-list.
4) Open the property window and check for the properties MenuItemType and MenuItemName.
5) Evaluate if there are values (in this case type Action, 'ProdMultiUserDefault') . If there was no values on these properties, it was related to a button where you needed to change/review the NeededPermission property as mentioned above)
6) Browse in the AOT for the menu-item.
7) Right click on the selected menu-item and choose: Add-ins > Security tools > View related security roles.
8) On this form you will see the information which roles, duties and privileges do have access to this menu-item.
9) In my demo environment only one privilege is used. This privilege is named 'ProdMultiUserDefaultProcess'. It appears that only one menu-item is member of this privilege.
10) You need to decide what to do. In my demo there is only one role which has access to this menu-item. Suppose there are 5 users and one needs to have this button available, I would choose to create a second role for the other 4 users. (try to avoid changing standard security objects)
11) Duplicate the role and provide a new name, label and description. The label descriptions should be unique in all languages you are using in your environment to avoid security errors.
12) Duplicate the duty which is also provided on the View related security roles. Then also provide a new name, label and description.
13) Remove the privilege 'ProdMultiUserDefaultProcess' from the duplicated duty.
14) Replace the duty on the duplicated role with the new duty.
15) Save and compile.
Now the already existing role can be used for user 'pjackson'. The new role with less access can be used for the other persons.
At some steps, also the security development tool can provide some insights and can help duplicating and replacing duties.
