Customer raises a incident stating while adding enclosures to record, he doesn't get the option to select public/private enclosures in one of the project, whereas in another project he is getting the access. What steps you suggest to correct it?

Instruct the customer to check if he has access to the option ‘Enclosure Access Control’ under the role configuration for any of the roles he is holding. This option will be available for the roles inherited from ‘Technician’.
