why my new custom field in lead search result view is not available in configuration?

Hi all,

I need to bring some field from related BO to Lead search result list. So, I open the CN RESULT of BT108S_LEA/Result, and created a new attribute linking to the related BO / attribute. After the creation, I can see the new field is added to the context node in View Structure tab. Now when I go to the Configuration Tab, I do NOT see the new field as available fields in the left hand side, thus not able to bring the new fields to the result UI.

I also tried to assign the new field to the designer layer (BT108_LEA / RESULT), it does not help.

Based on my understanding, this way to bring new fields on search result should work, but .....

I am on CRM 7.02. Anyone enhanced the search result could help?

Thank you very much.
