reference Field to only display user Id and not name

[David Cross]

This is my reference field in catalog item where only name is being displayed, please help me I only want the User ID to be displayed, what to do here 

I tired : ref_ac_columns=user_name > did not work 

User ID:

[Ankur Bawiskar]

Hi,

OOB on user table name field would be shown as system considers it as Display=true field

If you wish to show user ID then you will have to set Display=true on user name field but note this is platform level change

Is it not possible to show it in particular catalog Item requested for field [ ref ]

[Ankur Bawiskar]

nope

Once you select the user it would show name only

If you wish to show user_name when user types then you can use ref_ac_columns attribute
