I’m now Customizing the naming series for sales docs. I realize that I’d create invoice and include sales , it will only generate the Sales Invoice , if adding payment afterwards , it will have payment entry docs ( which I customize to become payment receipt ). So I’m thinking do I need use different naming series for Cash Sales ( include Pos during create invoice ) and Receive Payment afterwards or just use one set of naming series , want to seek for others opinion , kindly comment and thanks.
