Can anyone help me determine what the ^ and # mean when selecting a field in SuiteAnalytics Datasets?

The carrot I'm pretty sure represents the join. The # sign probably represents some iteration of the field. Like instead of having olsa_present_sku_display and olsa_present_sku_id, they just have one field with qualifiers. Mostly spitballing on that one. Take out the #display on one of them and see what comes up. I'm guessing it might be the Internal ID.
