AnswerClick to flip back
A
Return
💡 Explanation:
The Return port (R) is specific to unconnected Lookup transformations - it returns the lookup value to the calling expression. Connected lookups use Input/Output/Lookup ports in the data flow. The Return port does not exist in connected lookup configuration because connected lookups pass data through the pipeline.
