    Database constraint

    I have two table for which I want to make a link in the diagram but it seems for some reason, I am not allowed to do it. I am trying to join LA.LANo to LABook.LANo.

    Here is the message I get:

    table LA:
    LAID (Int)- Primary Key, LANo(nvarchar 15) Primary Key, supplierFID etc


    table LABook:
    LABookID (int)-Primary Key, LANo (nvarchar15) etc

    Any one can help me with this please?
