I'm brand new to XRMToolbox and have no idea how to use it so bear with me here. I am trying to import a list of data that is inaccessible to be imported into via the native import tool so I was told to use XRM toolbox. I have a file set up to import a set of data but when it comes time to select a unique identifier I cannot figure out what to use since those data points don't exist on the table I am trying to import. Has anyone had any luck using this tool or can you offer resources on where to look to learn about N:N relationships? I cannot find any good videos or resources out there. TIA!
