Available for Company, Available for department and Available for group related lists are not appearing on the Catalog Item form even though they are in the "Selected" slush bucket.
There is a OOTB system property called 'glide.sc.use_user_criteria'. with the Default value: true.
But, Entitlements are not honored if set to true. That's the reason we need to set this property to False in order to display the Available for options on the form.
The value of this system property governs an onLoad Client Script called 'Hide User Criteria Related Lists' which is hiding the Related List when the form loads.
1. Update 'glide.sc.use_user_criteria' the system property value to 'False'
After setting above System Property to 'false', fields like 'Available for Company', 'Available for department' and 'Available for group' appear on the form as expected.
