[JohnDF]

Hi everyone,

I need to change the display value of a reference field on case table.

Both fields a reference on asset table and I have set the serial number as display value for the asset table. But the problem is in the suggested spare part field are somethimes are asset which dont have seril number and than is the display field empty. How can I change the fields dispaly value for example to the display_value field on the case form for this requirement?

Thanks for your help.

Need thats in Display Value in the Reference field visible. But without invalid reference
