Hi @fatheyabdelslam,

if I understand you correctly you want to create a new record of “Clients Orders Monthly Invoice”, which has the link to the client. Then you want the script to fetch the client orders and populate your child table?

If this is the case, you could run a frappe.client.get_list and use the result to populate your child table. Something like

frappe.ui.form.on("Clients Orders Monthly Invoice", {
  client: function(frm) {
    // this function is called when the value of client is changed.
    // get all client orders of the current customer{
		method: 'frappe.client.get_list',
		args: {
			doctype: 'Client Orders',
			filters: [
				['client', '=', frm.doc.client]
			fields: ['name', 'order_number']
		callback: function(response) {
			var orders = response.message;
			if (orders) {
				// loop through orders
				orders.forEach(function (order) {
					// add child table entries
					var child = cur_frm.add_child('client_orders');
					frappe.model.set_value(child.doctype,, 'order_number', order.order_number);

You can extend the filters as required (I guess with a time filter as well). Maybe you also want to clear the child table before filling it again.

Hope this helps :wink:


this is more than i want i was intend to just filter the result and i’ll choose manually the orders
this is more advanced than my level
but thank you very much for this
