You can't join the two tables on order date since many tickets have the same date. So you get a many-to-many join. You need to rename Orderdate to something like Ticketdate in the ticket table and uncomment the %Key_Ticket... field so it joins correctly with Orders.
LOAD Date#(Date,'YYYYMMDD') as TicketDate,
[Paymode/PayLine/PaymNr] as PaymNr,
[Paymode/PayLine/PaymName] as PaymName,
[Paymode/PayLine/Qty] as [PayLine/Qty],
[Paymode/PayLine/Value] as Value,
FROM [..\..\..\..\qlikview\nieuwe export hq\FX20121103.xml] (XmlSimple, Table is [Tickets/Ticket]);
