Can a lookup transformation in SAS DI return multiple rows?

[LinusH · Accepted solution]

For a single base value, it will return maximum one look-up value (or values if you specified more than on look-up to target mappings).

If your lookup table contains duplicates on the look-up value, it will return the first match.

No. Exactly as Linus explained.

If you want this to happen then you will have to code it (user written transformation) - or you use a SQL join instead.
