Zipcodetable

Hi there, system: 3-tier Ax30SP3 (Citrix). We got some problems with the zipcodetable. When you want to open the tabel (for instance through field zipcode on tab Address of CustTable), Axapta seems to be searching for “quite a while” [V]. Does somebody have the same problems or maybe the solution? For an implementation in Germany I’m also looking for a German Zipcode table. Does anybody know which company can deliver this to me? Thnx, Johan
