==About==
* '''Status''': not useful at this point; filtering ''after'' this stage doesn't speed things up. The filtering has to be done ''before'' the grouping takes place. This query can probably be discarded.
* '''Requires''': {{vbzcart/query|qryPkgLines_qtys_done}}
* '''Returns''': sum of "done" quantities for all packages which have been checked in each order
** In other words, you get one record for each item in an order; that record gives the sum of quantities "done" for that item across all "checked" packages. This lets you know how many of each item remain open (to be filled).
** This was intended to then be filtered by ID_Order, so it wouldn't be pulling in a lot of data it doesn't need, but apparently MySQL isn't clever enough to figure that out; it still takes 30-40 seconds even when filtering for just one order.
** There is also PHP code somewhere which does this, but I needed to be able to pull these numbers up in w3tpl.
* '''History''':
** '''2011-05-31''' created for packing slips
