I have an GL Account UDF that is validated by a UDT and presents a lookup icon. I recently added several more UDFs, each validated by their own UDT, and they appear to be setup exactly the same way but do not present a lookup icon. I did setup the UDTs after the UDFs and then edited the UDFs to validate off the UDTs. Is that what I did wrong or is there a flag somewhere that determines whether there is a look up?
