If you dont care which description, then I would use an ApplyMap() to get the description. This functions much like a vlookup in Excel, so it will return the first match.
Create a mapping table:
Map_Names: Mapping Load Distinct
Now do an apply map:
LOAD <some key field>,
ApplyMap('Map_Names', ID) As Description,
Thanks Tresesco and Ashfaq; this is exactly what I was looking for. Wonder why it didn't appear to me at the first place .
Thanks Jonathan for your response. I didn't want to use it at the script level, as in the actual implementation, I have around 15 fields where I need this solution; and all of them come from different tables . Since I will be using it in just couple of tables, I would rather do it at design level
