How to pass variable from main pipeline to child pipeline in Azure Data Factory?

I have set variable "Id" in main pipeline and I'm setting value in "Set Variable 1" I would like to pass variable to child pipeline. I have created parameter "Id" in child pipeline. However I cannot refer to @{variables('id')} in Lookup5 of Child pipeline.

How to pass correctly variable?

Main pipeline: Main pipeline

Child pipeline: Child pipeline

  1. Go to your inner (child) pipeline
  2. Choose "Parameters" Tab
  3. Add a parameter, for example, childPipelineParam
  4. Go to your main pipeline
  5. Select your "execute pipeline" activity
  6. Choose "Settings" Tab
  7. in the "Value" field enter @variable("mainPipelineVariable"), or press "add dynamic content" and choose your variable from the list of all variables. Here "mainPipelineVariable" is the name of your variable you want to refer to the child pipeline.

Azure has a added a functionality to return parameter to the child pipeline using set variable activity. enter image description here

Here is the Azure Data Factory document link: Configure Pipeline Return Value in Child Pipeline

You should be able to pass the variable into the parameters of child pipeline. enter image description here

Simply access the passed in parameter with @{pipeline().parameters.Id} in the child pipeline. enter image description here
