Why can't I see "Sys ID" in UI Builder, in my Look up data source, as a field in Return fields?

Hello guys! 

As the title says, I cannot see the option/field under Return fields in my custom Lookup data source. Keep in mind that the column sys_id is available, but not visible in back-end.

Any ideas how I can make it show in the UI Builder?  

The use cause is to be able to do like how he does in this youtube tutorial video at 1:10:00.

@ronro2 sys_id is available on every table but is it not available on list view to be selected in classic view as well.

Like on incident table, you cannot configure list layout to show sys_id. There is a different configuration for that. What is the use case here?

@RaghavSh hey mr, I've updated what is the use case. 🙂 Please read again.

Hi @ronro2 ,

You cannot select sys_id from the field selection, however sys_id returned by default as a unique value with the result.

Thanks
