Purchase Invoice - can't create says must be non-stock item

I am testing ERPNext Version 15 and i’ve created a purchase order for a regular stock item. I created a purchase receipt for the PO, and then tried to create a purchase invoice, but am getting a popup that says “Item IXD-360 must be a Non-Stock Item”. Can someone explain the reason for this? We are currently using Version 9 in our live environment and it works fine, but in Version 15, this error occurs. Is there some setting that we need to change?

Thanks in advance.

Regards,

Jeff

Make sure item master has stock item :white_check_mark: maintain stock

Dear pra17shant,

Yes that box “Maintain Stock” is checked on the item. This is why i don’t understand why i’m getting the error. It says in must be a non-stock item.
