What is significance of 'Sales Organization Hierarchy' Check box while running the collections.

Summary

What is significance of 'Sales Organization Hierarchy' Check box while running the collections.

Content

In 'Collect Planning Data' Run-->Under Demand Management Tab-->We have an option 'Enable Sales Organization hierarchy collection' 

 What is this option used for? 

What data does it collects from OPS if the the check box is enabled during collection?

Is this check box option linked to any of the 'Dimension Hierarchy' in the Planning analytics Area?

We just want to make sure if we can leverage this option in our Implementation Project which might benefit our client.

Any suggestion on this topic will be a great help to us in the project.
