How to add a field on sub-panel like Role field, we can find on Opportunities ?

Francesca Shiekh I have manage to add the field but I am having issue on display it now.  The issue I am having is to display the list . 

Sorry Rodrigo Manara, I've not tried anything like this since v6.x (Gave up in v.7.0 and went another route). Perhaps André Lopes has more experience with this kind of change?

No worries, I am on the right track now, I figure it out. I will post here soon 

field needs to be create using a custom query , I have manage to complete the code now.  Also Needs to override the Relate Api update so the data is updated in sugar that way on the update response you need to ensure the data also have the new field created. when the response come it includes the new field in.
