The Order's "Großschäffer" was one of the leading functionaries of the order. The word translates about as "chief sales and buying officer" with procuration. They were in charge of the considerable commerce, import, export, crediting, real estate investment etc., which the Order carried out, using its network of bailiwicks and agencies spanned over much of Central, Western and Southern Europe and the Holy Land. The other Großschäffer in Marienburg had the grain export monopoly. As to imports both were not bound to any particular merchandise. From Königsberg, holding the monopoly in amber export, achieved the exceptional permission to continue amber exports to Flanders and textile imports in return. On the occasion of the ban on Flemish trade, the Hansa urged Prussia and Livonia again to interrupt the exchange with Novgorod as well, but with both blockades Russian and Flemish commodities could not reach their final destinations. In 1392 it was then Grand Master Conrad of Wallenrode who supported the Flemish to achieve an acceptable agreement with the Hansa resuming the bilateral trade. While a Hanseatic delegation under Johann Niebur reopened trade with Novgorod in the same year, after reconfirmation of the previous mutual privileges.
