I am just starting here hence my qusiotn may be silly.
\nI assumed that the flow for a given article was clik -> cart - order, i.e. that to be ordered an article had to be first put in a cart.
\nYet, some sessions start with a cart, and some start with an order. Here are the value counts of the first type in a session (0 is click, 1 is cart, and 2 is order):
\n \n \n \nHere is an example of a session starting with an order, namely session 6247320:
