In one Catalog server below property option "Show only assigned items of a request to assignee (Restricted view)" is showing, but not in another install.
CA Service Catalog 17.4
The mentioned row was missing in the table usm_configuration.
This configuration option is not available by default. Run the following DB query to add:
insert into usm_configuration values ('request','restrict_assignee_view','INSTALLED_DEFAULT',2,1,0,0,'111,114',NULL,NULL,NULL)
Restart Service Catalog services for the change to take effect.
