How to change field display value on a reference field.

[Michael M1]

On the Change Request form I have a reference field that points to 'cab_meeting' table.

When the user selects this field a list of upcoming cab meetings are displayed. They are displayed by name with start date as an additional column. When the user selects the meeting the field just shows 'CAB Tuesday meeting' but I want it to show the 'start' column (e.g. 23-Nov-2018). 

How can I make the display value on this form be start date without changing the display value for the table in general. 

I have a similar request for a user to choose a country from the cmn_location table but without changing display value on that table as well.

Thanks for the help.

This did not explain how to dot walk for choice field. It may not be possible.

Hey Michael, 

You can also make changes to the variable attributes of the reference field in the child table, without changing its display value. Here's the link to it :
