How to use NX expression to send value to TC Attribute

Hello,

I have few lines of the NX Expression. I would like to send them to TC attribute.

For sample: In NX, we have expression. A="Car", B=1, C="Taxi"

I want to send this context A="Car" to TC attribute ID: "Item type".

Result: TC attribute, Item type="" => Item type="Car"

Best wishes!
