Hi- I had added a field called Purchase Order (po_no) and Purchase Order date (po_date) to the Sales Invoice doctype from Customize Form.
I had to do a bench update, and after this, I am not able to customize the sales invoice any more. I get the error: Fieldname po_no appears multiple times in rows 6, 24
I think a new field was added in the latest update and it has the same name as my custom field. Please help resolve.
Thanks in advance
