%Y%invoiceSequence:5. Before the first % symbol you can put any number or any letter or left it blank. Variable %y means year. Use upper case %Y for format 2018, use lower case %y for format 18. In the next year, the system will automatically fill currently year, without any manual changes in administration. Variable %invoiceSequence is order sequence number of invoices. You can set this value in the field Ordinal invoice number. Variable %orderSequence is separate order sequence primarily used for numbers of orders. Variable %orderYearSequence is separate order sequence, for which the numbers will be reset to 1 in the next year. Number after colon that is after variable %invoiceSequence, %orderSequence or %orderYearSequence means number of digits of final number. For lower numbers the missing digits are filled with zeros. Examples. A%Y%invoiceSequence:3 — Invoice number will look like this: A2018001. %y%invoiceSequence:2 — Invoice number will look like this: 1801. %Y%invoiceSequence:4— Invoice number will look like this: 20180001.
