To enable this menu option, follow the steps below in Portal.
From the dashboard menu, select Security Dashboard.
Click Menu Profiles.
In the search field, search for the leaver menu profile e.g COREPORTAL_LEAVER.
Click the three-dot icon then select Manage Menu Options.
To filter the systems, click the filter
icon.
From the Filter By System dropdown menu, select CorePortal Pay and Web services.
Click Apply then in the search field, search for the following menu option Widget - Pay - P60 list.
Enable the toggle for the menu option above.
