JBA ML - Purchase Orders

["Greg Wieczorek" <wieczog@xxxxxxxxxxxx>]

At the start of the year, we switched to average costing for purchase parts.
All purchase parts have a purchase burden. The burden percentage varies by
vendor. We coded the burden percentage as a landed cost for each item and
supplier. Any purchase order that was entered before the start of the year,
when received in stores, does not have the burden applied. Any purchase
order that was entered after the start of the year, when received into
stores, does have the burden applied. Any suggestions on how to get the
burden applied via landed cost or otherwise to POs entered before the new
year?
