UDT with Formatted Search

Hello,

I created a UDT with two fields: ItemCode and ItemName. I want the ItemName to be updated automatically based on the ItemCode.

At the moment, I have created a Formatted Search (FMS) on the ItemName field. However, the value is not updated automatically in the UDT. When I click the lookup/magnifying glass icon, the FMS works correctly and retrieves the ItemName, but it does not refresh automatically when the ItemCode is entered or changed.

Is there a way to make the FMS update the ItemName automatically based on changes to the ItemCode field?
