Dea Friends , I am facing a below problem. I am creating a custom list for Assets . I have created Asset ID , Serail Number. If i am filling pcs-001 in the asset ID for first PC , and complete the first form. My manager wants that the same asset ID should be entered in the further forms . System should restrict to enter the same asset ID in further forms. Is it possible. I am using WSS 3.0. Please help

I'm a little confused on the question. Do you have multiple lists? You can do a lookup based on Asset ID for other lists.
