Let’s say my company is doing both retail and wholesaIe. So, I created a POS setting for series-SINV. This works fine when create Sales Invoice, IsPOS is checked.
But for standard/wholesale transactions, I leave IsPOS unchecked but I cannot add products…it said "Please specify customer. It’s needed to fetch item details. I already selected a customer but it’s refreshed back to empty again everytime I add products… Why?
It seemed the system now reads series SINV as POS so cannot do standard invoice again, is it? How to make both POS and standard invoice available?
