Hi guys,

I thought I would jump in on this since I was working through the same issue in Kingston.   I was able to configure the functionality to work as expected by doing the following.

1:   Created a new Service which created a Case on the "sn_hr_core_operations" table.  

2:   Added a custom field "HRITReason" to the COE table and added it to the form.

3:   Modified the UI policy Kiel listed above, "Hide HR service fields and related lists".   I did an insert and stay on the action as I could not create a new UI action from scratch.

Once I did this my new field displays on the case based on it being configured on the HR Service "Service Table fields".

Regards,

Matt
