How to modify Configuration Line details for sales order

When open configuration Line for sales order ( open sales order and in sales order line Tab there is button to open Configuration as shown in below),I am working Ax 2012 R2

When I click on Configuration Line it will open below form and in the below form I want to change the names of attribute values of an Item

At the moment above values are coming from the EcoResAttribute table and field name is “Name”.

Now I have another custom field in the same table and I want display value of the custom field .

Please suggest any Idea,I have debugged the code of clicked method of Configuration Line menu button but Could not find how those values are displaying the above form.
