Exclude Blank Access As
When selected, the system ignores all event handlers with an Access As identifier that is null (blank).
The setting of this option can, to an extent, override the settings of the Exclude Access As field. Even if that field is left blank (in which case, all event handlers would normally be recognized), this check box causes the system to ignore event handlers with a blank Access As field.
You can use this check box to quickly and easily disable all customer event handlers for troubleshooting and diagnostics activities. You can also use it in conjunction with the Exclude Access As field to disable custom event handlers without having to list them all.
