From Bus Name Column
Column Type = Text
The optional, informational From Bus Name column contains the name of the “from" bus for the line or transformer indicated, as listed in the LoadFlow_Bus table of the Network Definition Dataset used for the study.
NOTE: This column can only be used as the ID when all bus names in the loadflow are unique. See Create Unique Bus Names to automatically create unique names.
If the From Bus Name column does not exist, or the input bus names are not unique, the model will look for and use the From Bus Number column for the ID.
