Output index function is used in reformat having multiple output ports to direct which record goes to which out port.
for eg. for a reformat with 3 out ports such a function could be like

if (value=='A') 1 else if (value=='B') 2 else 3

which basically means that if the field 'value' of any record evaluates to A in the transform function, it will come out of port 1 only and not from 2 or 3.

If you want to send one input record to only one output port we can use the output index
