How to display short description instead of number when selecting value for a reference field?

[Mike_R]

If you want to do this for all task types, go into the dictionary entry for short description and set display to true

instanceName.service-now.com/nav_to.do?uri=sys_dictionary.do?sys_id=244e166aa5300110c0a0e1db2cdc9529%26sysparm_view=advanced

Then go into the entry for number, and set Display to false

instanceName.service-now.com/nav_to.do?uri=sys_dictionary.do?sys_id=6c4e166aa5300110c0a0e1db2cdc9527%26sysparm_view=advanced

If you are looking to do this for a specific table and not all tasks tables, set the display in the dictionary override instead

Here I am trying to get Incident short description value instead of incident number from the reference field on a custom table. By setting dictionary override display value to true doesn't help to bring incident short description value. Is there a way where I can only get incident short description instead of incident number?

After setting short description display as true, did you also set the number display as false?

As per requirement I need both field values on custom table.  'Incident number' as well as incident 'short description'. So, Incident number I am getting but not incident short description value.
