Lookup Transformation.Give me one or two examples please?

where as unconnected lookpup t/r not connected other t/r in the pipe line and it recive input data from the result of :LKP Expression in an other t/r,that support expressions.

2)Connected lookup support user defined functions
Unconnectd doesn't support user defined functions.

3) It returns multiple output values to other t/r
Unconnected returns single output value to other t/r.
