Get item based on custom field i added in Item Doctype

how to get an item based on it’s number .?
i am trying to do this in stock Reconciliation .
i added a custom ‘Link’ field in stock Reconciliation Item doctype . How can i get the only item attached to this number ?

any help please ?


You need to make a script for this, you can try the below scripting:

frappe.ui.form.on('Stock Reconciliation Item', {
  item_number: function(frm, cdt, cdn) {
    const row = locals[cdt][cdn];
    if(row.item_number) {
      frappe.db.get_value('Item', {'item_code': row.item_number}, 'name', function(data) {
        frappe.model.set_value(cdt, cdn, 'item_code',;

This script monitors the custom “Link” field (named “item_number”) in the Stock Reconciliation Item doctype and responds to changes made to it. Upon modification, it employs the frappe.db.get_value() function to retrieve the name of the item associated with the item code entered in the custom field.

Once the item name is obtained, the script leverages the frappe.model.set_value() function to assign the item code value to the “item_code” field of the current row.

Hope this will help you out.

Thank you.
