My priorty is not changing for a custom table inheriting Incident Table

[Navaneeth1]

I have a custom-scoped application with a table inheriting from the incident table. I have Impact, Urgency, and Priority inherited from the incident table for this scoped application table and I've created Priority lookup rules but the priority still does not change when I change impact and urgency for this. 

Could someone please help me fix this issue?

Hi @Navaneeth1 ,

You will need to create the Priority lookup rule for your custom table properly, for that:

1)First you need to create a table extended by data lookup matcher rules(dl_matcher)table.

2)in this table create 3 fields below:

Impact, urgency and Priority

and set the value next process is 

3)create Data Lookup Definitions like this

I followed the YouTube video, and though my lookup has the "Run on Change" flag marked as true, it will not update until I save the record.  Did I miss something?
