As mentioned in the preceding section, unconnected transformations are not connected to any other transformation or source or target by any links. Unconnected lookup transformation is called by another transformation using the :LKP function. Using the :LKP function, you pass the required value to the input port of the Lookup transformation, and the return port, in turn, pass the output value back to the transformation from which the lookup was called. A mapping using unconnected Lookup transformation is shown here:
In the preceding mapping, we are implementing the same scenario we implement using Connected ...
