Hi Mark,
Unfortunatly no is the answer. I have no way to alter anything at the universe level. This partucular universe is owned by another area of my organisation and even simple changes go thru a 12 month change management process, significant design changes to the universe I would not even bother considering as I'll have retiured before they have been actioned.
This is why I thought creating a custom function to be published into BO for use that would allow me to construct code to take a variety of date objects and then return the greatest however I have never writtn functions for BI before and have no idea where to start.
I can certainly construct the code in say VB or any number of web server languages but I am guessing it would be written in C or something like that that makes me need to go for coffee.
