How to bulk create item structure from "Create from common" using FBDI

Content (please ensure you mask any confidential information):

In our project there is requirement to load item structure via FBDI. The structure should be referenced from master org to Child org. In item UI structure tab, this functionality is referred to as "Create from common". So when child org structure is referenced to master org, structure cannot be edited in Child Org but i can be edited in master and changes will propagate to child org. While i am aware about how this works via UI, need some help on how to populate data in FBDI for bulk load (as i am getting error while loading the data).
