I have to enter the same phrase on certain sales invoices for a negative value. Using 'M Message Line' in Product Code column is time consuming. Currently having to memorise an invoice template with this phrase using 'S2 Special item'. Recall the invoice then insert rows to move text as I wish it to appear at the end of the invoice. Product code would be useful if the value entered was to be a positive number. I need my value to be negative. The workaround I have to do is time consuming and clunky. Can't use discount as some invoices already have discount applied - this is a government discount scheme
