The Remap action node enables you to replace the value in a variable with another predefined one. If the value is matched and replaced, the step will follow the “Yes” flow, otherwise it will follow the “No” result.
In the above example, if the initial value of the variable 'Operator' was '1' then it will be changed to 'MTN' and the 'Yes' step will follow. If the initial value of the variable was '4', then nothing will be remapped, and the 'No' step will follow. To refer to the remapped value in another node, use [[variable:result]]
