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".
