Edited By: Shubhali Agarwal
Use Cases - When to use this command
To ignore/remove any row(s) from the generated output CSV file, for a particular output value.
Description
NOOP instruction is used inside a node when we want to ignore/remove any row(s) from the generated output CSV file, based on a certain output value.
Guidelines for Usage:
DO NOT USE in the root node.
Use only when providing input as a CSV file.
This instruction can also be generated by choosing "Ignore Row" option from a node's wizard.
How to use this command
NOOP command is for node level operations. It can be used in any node as an instruction, except for the root node.
It should not be used on the Arrows.
Let's take an example: "$val1" and "$val2" are being sent as inputs to the analytics tree from a CSV file, and we want an output variable "$result" having the value either "true" or "false" based on whether "$val1 > $val2" or not.
NOOP instruction can be used to ignore/remove the rows in the output CSV file generated, for the row(s) for which "$result" would be "false".
