Total order Quantity in Characteristic.

HI Experts,

I need to bring Total order Quantity (CAUFVD -GAMNG) to Characteristic value in characteristic in (300) Class.

I have created one Characteristic Total order Quantity & assign the field CAUFVD GAMNG in reference to Table field in Additional data & assigned the characteristic to the Class (300).

I have created the Prod order , but i can not see the quantity in characteristic values.

Is thia scenario feasible ? If Yes, What setting i am missing.

Thanks & Regards,

Priya
