You will need to write custom script to make it work. For example, please check this post.

Calculate Total Qty of items table of Sales Invoice

frappe.ui.form.on("Sales Invoice", { validate: function(frm) { total_qty = 0; $.each(frm.doc.items || [], function(i, d) { total_qty += flt(d.qty); }); frm.set_value("net_weight", total_qty); } });
