    If you want to follow "AX2012 way of doing", you should use SurrogateKey as PK and your composite key as a replacement key.

    I agree with Martin, try to keep RecId are your PK and make your composite key the replacement key. If you really need the composite key as the primary, you have to set the "allow duplicates" to "no" and the "alternatekey" to "yes" on the index. If you then save the table, then the index will be available for selection in the primaryindex property.
