How to add multiple fields (listing sizes) in Sales Invoices

New to ERPNext.

I need to add multiple columns or fields to the sales invoice, so we can break down the size for each quantity of the product (row) billed to the customer.

I tried going to custom fields, and adding a new custom field, but it did not appear.

Can someone help?

Thanks!

This should show up the custom fields that you have added to your Sales Invoice.

Hi @mot

Disable Compact Item Print on the print settings form and check

Thanks
