I noticed some payments in our database have orders attached and others don't. Why is that?
Any transactions entered through the Daily Sales, Advanced Sales, Group Sales or Online Sales screens will have two parts; an Order and a Payment. Since multiple types of items can be grouped in these screens for purchase (e.g. tickets, a donation and a merchandise item), Altru uses an Order to collect these items into one transaction with one Payment.
Any transactions entered in the "Back Office" using Add a Payment, Add a Membership or Batch Entry will have a Payment component but not an Order.
