If the data area flag called Function level security is set to Y, LANSA function level security is always enabled. This means that every time a process menu is displayed a check must be made against all associated functions and attached processes/functions to determine if the user is authorized to use them.
If the user is not authorized, the options involved do not appear on the process menu.
While this facility provides a simple and easy way of building variable menus by user, it requires system resources to perform the security checks.
If you have no need to build user variable process menus, consider setting the system flag to N to indicate that function level security is not required.
This data area flag is changed on the 6.2.5 Execution and Security Settings,
