Custom access control and logging

SQL Call: Custom access control and logging

Use this call to restrict which entries a user is allowed to view and edit, and to log which entries a user views.

Access to a menu item is normally controlled through functions and roles alone but some entities need more fine grained control. For example, a user may have access to the View Member menu item for normal members but not for members with a protected identity.

The menu items a user visits are always logged (in ADMINLogMenuItem) but for sensitive data you may need to log exactly what entries are viewed. Do the logging in this call as the common ways of viewing data (grid and InfoSQL) are not allowed to modify the database.

If you bind a scalar function instead of a stored procedure to this call then its name must end with '_GrantAccess'.

May modify database: Yes

Resultset: Access permissions

Return whether the user is allowed to visit the menu item with the current parameters.
Table count: repeated exactly once
Row count: exactly one row
Columns
GrantAccess mandatory bit
1 if the user is allowed to view the menu item, 0 if the user should not be allowed to view the menu item.

If 0 then an error will be logged as the user should not have been able to reach the menu item with the given parameters in the first place.

Querystring parameters

menuitemheading optional
String that replaces the menu item name when the menu item is loaded. It does not replace the name before that (like for example in the navigator). It is ignored if the menu item is displayed as a part in a multipart in which case the name can be set from the multipart procedure.
