THIS IS MY SALES ORDER
THIS IS MY SALES INVOICE
Hello,
In the Sales Invoice, Sales Order ID is updated in the Sales Invoice Item table. For the quick solution, you can make this field/column visible in the Print Format.
Is this standard? I don’t have a sales order number on my sales invoice anywhere even though I am creating sales invoice from sales order. Thanks!
Easy way you add new field sales_order (link to Sales Order) in Sales Invoice Form => When you create IV from SO => This field will update and can get this field to print.
Wow! That was easy! Thanks for the assist.
