Unique error message Need Help

[NCP]

Hi @ErpnextRaja,

@avc is right; if you want to change the message or something else, then you have to add a custom function, or you can also apply the server script.

Please check the reference:

Customer Name is not Unique

So you have to apply the server script using validate or on_update method. existing_customer = frappe.db.get_value("Customer", {"customer_name": doc.customer_name}) if existing_customer: frappe.throw("Customer with the same name already exists. Please choose a different name.") Output: [image] Thank You!

Thank You!
