In some publications, Arts Council England have referred to an "Enhanced Report" within Audience Finder that Band 2 and Band 3 NPOs must submit from 2019 onwards.
However, when you go into Audience Finder 2.0 BETA reports section, you will not find an "Enhanced Report" that you can run. This is because there is no enhanced report: it is the inclusion of the protected characteristics within the survey data that is summarised in the standard Audience Report that makes it “enhanced”. It's the data that is enhanced, not the actual report itself.
Basically, as long as you have submitted survey data into Audience Finder that includes responses to all of the Audience Finder survey's core questions, and you check the “Use Survey Data” checkbox when creating the standard Audience Report within Audience Finder, you will be creating the correct report.
