Question
What is the difference between a connected look up and unconnected look up?
Answers
When the inputs are taken directly from other transformations in the pipeline it is called connected lookup. While unconnected lookup doesn't take inputs directly from other transformations, but it can be used in any transformations and can be raised as a function using LKP expression. So it can be said that an unconnected lookup can be called multiple times in mapping.
