How to change standard class private section code

Question

Dear experts,
I need to add new attributes in a standard class as per one OSS note. I took access key to add new attributes. I have a question.
class name: CL_J_1BEFD
Attribute: MT_GROUP_C350
Level: Instance
Visibility: Private
Type STANDARD TABLE OF mty_result
How do i add the instance attribute because i do not want to give the typing and associated type. instead i have to declare data: MT_GROUP_C350 type standard table of mty_result in class builder private section code.
if you look at the pushbutton between Associated type and Description, for all instance attributes there's a green color lining below the arrow. I want my attribute also to be exactly same.
Though i have access key, in private section the display<->Change button is disabled.
Please suggest me how do i add code in private section of a standard class. i have required access key to change the class.
Thanks,
Rajesh.
