do you mean create 2 foreign keys, one for AssetIDx pointing to AssetID and the second AssetIDy pointing to the same field?

or do you want to build a query, to return the 2 different Asset Names ?

select t2.*, a1.Name Asset1, a2.Name asset2
from Table2 t2
left join table1 a1
  on a1.assetid = t2.AssetIDx
left join table1 a2
  on a2.assetid = t2.AssetIDy

ALTER TABLE table2 ADD CONSTRAINT FK_table2 FOREIGN KEY
      (
            [AssetIDx]
      ) REFERENCES [table1] (
            [AssetID]
      )

you neet to create two references

ALTER TABLE table2 ADD CONSTRAINT FK_table2_AssetIDx FOREIGN KEY
     (
          [AssetIDx]
     ) REFERENCES [table1] (
          [AssetID]
     );

ALTER TABLE table2 ADD CONSTRAINT FK_table2_AssetIDy FOREIGN KEY
     (
          [AssetIDy]
     ) REFERENCES [table1] (
          [AssetID]
     );

PFFFFFFFF,  I'm stupid sorry,  I had already done what you all suggested and it didn't work because I had another reference (which I didn't mention) set to cascading Update/Delete if I remove that it works.

I'll just distribute the points to everybody that commented, sorry to have waisted your time :=)
