This is where the relationship of configurator products are configured. This is done by importing a spreadsheet file that contains all product configurator products and options and their relationships to one another. The Headers Info section contains the fields that are part of the import configuration process.
You may export a template by clicking Export (note that this will also export any existing configuration for configurator products as well). Modify the spreadsheet accordingly and Import it back in to add/remove/update the configuration for configurator products.
