Mailmerge in Navision.

Hi, I try to setup a mailmerge in Navision. Right now I’m able to create a mailmerge file of ShipmentHeader data and attach it to a template document. I’m using automation servers: ‘Microsoft Word 10.0 Object Library’.Application and ‘Navision Attain ApplicationHandler’.MergeHandler. However, I want to add shipment lines to this template document. How do I do that? Thanks, Roelof.
