Does anyone know how the Order number increases in Drupal Commerce?
Obviously when someone puts in a new order the order number will be AT LEAST one larger than the previous order number, but other than that why would the order number increase?
For example while testing the site my first order # is 1 (duh), but then 19 days later when I tested it the order # was 19, without any other tests occurring in the interim. The following day I did a test transaction and the order # became 31.
It keeps going up every time I test it but it doesn't just increment by one every time. So I'm just curious why it might be behaving this way. Anyone know?
