Hi
i need to make an invoice(report) with nummbers (like 1/04, 2/04...) but
each Customer must have invoice starting with 1/04 referring to the date
they must pay.
An example
Customer: Something
MustPay_Date: 27/06
Invoice_NR: 01/04
following
MustPay_Date: 30/06
Invoice_NR: 02/04
but
Customer: Something Else
MustPay_Date: 27/06
Invoice_NR: 01/04
Any sugestiones about the expression solving this problem?
many thanks
