in Customer, there is field of naming_series.
the effect of series in customer like (Customer Series: CST16001):
So i using the code below to pull customer series no in quotation print format.
{% set u = frappe.get_doc("Customer",doc.customer) %} {{ u.naming_series or ''}}
but the effect is that, Customer Series no(CST16001) doesn’t display, only display series prefix (CST.YY…###),
Please help to check what’s problem and how to correct code.
