Override the original source code functions

I have created custom scripts and server scripts to modify the existing method in Python of the original ERPNext. I realised that for the same event, the original codes will run after the custom script’s codes. Is there a way to only run the event on custom script?

what is the code ?

I want to change the formula to calculate the fg_completed_quantity.

Here is my code for custom script in ERPNext.

frappe.ui.form.on('Stock Entry', {
work_order: function(frm) {
	if(!frm.doc.work_order || frm.doc.job_card) {
    var fg_completed_qty;
	return frappe.call({
		method: "get_work_order_details2",
		args: {
			work_order: frm.doc.work_order,
			company: frm.doc.company
		callback: function(r) {
			if (!r.exc) {
				$.each(["from_bom", "bom_no", "fg_completed_qty", "use_multi_level_bom"], function(i, field) {
					frm.set_value(field, r.message[field]);
		        fg_completed_qty = r.message.fg_completed_qty;
				if (frm.doc.purpose == "Material Transfer for Manufacture" && !frm.doc.to_warehouse)
					frm.set_value("to_warehouse", r.message.wip_warehouse);

				if (frm.doc.purpose == "Manufacture" || frm.doc.purpose == "Material Consumption for Manufacture" ) {
					if (frm.doc.purpose == "Manufacture") {
						if (!frm.doc.to_warehouse) frm.set_value("to_warehouse", r.message.fg_warehouse);
					if (!frm.doc.from_warehouse) frm.set_value("from_warehouse", r.message.wip_warehouse);

To override methods, you can use hooks in a custom app. See here:


okay , what is the event ? and why are you creating an script type api ?

My initial thought was to override the frappe whitelisted python method and found out that the API server script can be called by frappe.call

Hey, did you find out the way to implement hook?

Thank you!
