In this example we have considered an Incoming Dataframe with following rows:


DATA_COLS

::

    -------------------------------------------

CUST001INV00120200101PRD0011200

CUST001INV00220200202PRD0022200



Generate UUID node Configuration and Output
+++++++++++++++


GenerateUUID node is configured to generate UUID for each row and add it as a new column [UUID_VAL]. 

Outgoing Dataframe would be created as below with new column [UUID_VAL] added to it:


::

    DATA_COLS                           |    UUID_VALUE
    ------------------------------------------------------------------------------------
