Check this thread:

Calculate Total Qty of items table of Sales Invoice

I wrote the following custom script but it does not work. 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.doc.net_weight = total_qty; } });
