SELECT     dbo.Certificate.Cert_number AS Certificate, dbo.Certificate.Cert_inbound_date AS date, dbo.Certificate.Cert_trans AS Tr, dbo.Certificate.Cert_net AS net,
                      dbo.Customer.cust_name AS Customer, dbo.Certificate.Cert_trk_license, dbo.Certificate.Cert_Front_trl, dbo.Certificate.Cert_Rear_trl,
                      dbo.Commodity.Commod_name AS commodity, Customer_1.cust_name AS Carrier, dbo.Certificate.PK_Certificate
FROM         dbo.Certificate INNER JOIN
                      dbo.Commodity ON dbo.Certificate.FK_Commodity = dbo.Commodity.PK_Commodity INNER JOIN
                      dbo.Customer ON dbo.Certificate.FK_Customer = dbo.Customer.cust_pk INNER JOIN
                      dbo.Customer AS Customer_1 ON dbo.Certificate.FK_Customer2 = Customer_1.cust_pk

In the sql management studio this will return the expected data. dbo.Certificate.PK_Certificate is the primary key in dbo,Certificate, this was the field I specified in the BO mapper, is that correct. Still no results in the browseDialog.

For a View, you need to have a Pk into it, and the override the primary key once in the BO Mapper, have a look at this picture:

Any ideas?
