Hi Steve. PMFJI but I think what Wayne is asking is why one cannot use a UDF in an index and the short answer is you can. Its ok to do so but adds an additional level of complexity to the structure. In addition, it would appear to not be optimal or perhaps even necessary in his particular post.

>>I have 1 parent table, 2 child tables and 1 grandchild table. I can relate the parent to 1 child and then to 1 grandchild. I cannot relate the parent to a second child table in a view (according to the view wizard). I still don't understand why I can't get an index based on a UDF to work. Nobody has really addressed that issue.
