Work orders delivered quantity in coois

Hi Experts,

May I ask how can I obtain the delivered qauntity of a WO line item?

I looked at 'Technical Information', it shows the field is 'CAUFVD-GWEMG'.

Path:

T-code: coois > select an order >Delivered

In addition, I want to ask how to trace back to the table field. As I check in Technical Information, it may not be a table field and I do not know how to trace.

BR,

King
