How to auto update attributes based on other attribute values.
One answer
This is a typical "dependent enumeration" scenario which can be easily implemented.

Of course you can also use Calculated Attribute Customization for which there are many samples on the forum.

Thanks very much for the response.
I set up a value set customization between Priority and Severity with the necessary mappings, and on the Severity attribute, I have it using that Value set with dependencies projectArea & Priority.
What I am seeing is that when I set Priority the desired work item severity doesn't move even on save, any ideas??
If you use a Value Set, it's possible that the new value in the altered value set does not get "selected" automatically. In this case, you will have to use the Calculated Value option.
A value set only provides you the choices, it does not automatically set anything. If you want automation to set values you need to use other options such as a calculated value, which would require JavaScript or Java.
