Hello,

How can I add "None" as the default value for a Reference variable on a Catalog Item?

Thanks!

Hi Michael,

Reference fields/variables point to a table of records. Unless you have a record with a display value --None-- (or similar), this doesn't exist for reference fields.   Normally a blank field is sufficient to indicate that nothing has been selected.

What is the underlying business requirement you need here?

Hi Chuck,

Thanks for the quick response.

I am building a cat item that will be posted to our Service Portal. We have a mandatory field on the cat item that references cmdb_ci_service. We want to give users the ability to select "None" if they can't find the appropriate entry on the list of CI's.

Then I would make a CI with the name "Unknown", "Unavailable", or something similar to allow them to pick it. You can always set it as your default value if needed.

Hi Michael,

I agree with Chuck on this one.
