Dictionary override display value not working

[Marton]

Hi guys,

I have a reference field on the Issue table to the Task table, and I want to change the display value there to short_description

any idea why is this not working? It still shows the task number on the field.

Override Display Value takes whatever column you're on and makes that the display value for the table, regardless of what the parent table's display value is.

I see so it I wanted to show the short description on the sc_task level for the RITM instead of the RITM number I would put a dictionary override on the sc_req_item table for short description to over ride the display value.  Not that I think I would ever what to do that.

that is exactly how it SHOULD work... from the kb...

Select the check box to use this field as the display value on the extended table.

For example, the Story [rm_story] table uses the short description as the display value in reference fields instead of the number, as defined in the Task [task] table.

if that is not behaving correctly i suspect there is an issue and would open a hi ticket... the issue MIGHT be involved in the fact that the issue table extends the planned task table, which extends task... so they MAY not have the back ground process that does this looking at this correctly.
