I have a requirement to validate payment cards from one universe against a definitive list of valid payment cards from another universe and to only use the payment card from the first universe once it has been validated against the list on the second universe.
I can create seperate data providers for each, but am finding it difficult to link the providers together as BO appears to link every row on the first universe with every row on the second ???.
