# Report for Wares.
# Warning, deep magic ahead.
# This function gets all parts from the database according to the filters specified
#
# specials:
# sort revers - sorting field + direction
# top100
#
# simple filter strings (every one of those also has a column flag prefixed with 'l_' associated):
# partnumber ean description partsgroup microfiche drawing
#
# column flags:
# l_partnumber l_description l_listprice l_sellprice l_lastcost l_priceupdate l_weight l_unit l_rop l_image l_drawing l_microfiche l_partsgroup
# l_warehouse l_bin
#
# exclusives:
# itemstatus = active | onhand | short | obsolete | orphaned
# searchitems = part | assembly | service
#
# joining filters:
# make model - makemodel
# serialnumber transdatefrom transdateto - invoice/orderitems
# warehouse - warehouse
# bin - bin
#
# binary flags:
# bought sold onorder ordered rfq quoted - aggreg joins with invoices/orders
# l_linetotal l_subtotal - aggreg joins to display totals (complicated) - NOT IMPLEMENTED here, implementation at frontend
# l_soldtotal - aggreg join to display total of sold quantity
# onhand - as above, but masking the simple itemstatus results (doh!)
# short - NOT IMPLEMENTED as form filter, only as itemstatus option
# l_serialnumber - belonges to serialnumber filter
# l_deliverydate - displays deliverydate is sold etc. flags are active
# l_soldtotal - aggreg join to display total of sold quantity, works as long as there's no bullshit in soldtotal
#
# not working:
# onhand - as above, but masking the simple itemstatus results (doh!)
# warehouse onhand
# search by overrides of description
# soldtotal drops option default warehouse and bin
# soldtotal can not work if there are no documents checked
#
# disabled sanity checks and changes:
# - searchitems = assembly will no longer disable bought
# - searchitems = service will no longer disable make and model, although services don't have make/model, it doesn't break the query
# - itemstatus = orphaned will no longer disable onhand short bought sold onorder ordered rfq quoted transdate[from|to]
# - itemstatus = obsolete will no longer disable onhand, short
# - allow sorting by ean
# - serialnumber filter also works if l_serialnumber isn't ticked
# - sorting will now change sorting if the requested sorting column isn't checked and doesn't get checked as a side effect
