How to create Geomap while using HANA analytic view ( HCP) as a datasource?

Hello Experts,

I am referring to this blog - Cloud for Analytics and Geo Locations - Part 1 and while I try to execute the same steps to create a Geomap on BO cloud, I do not get any option to change any of my dimensions in the model. I am using SAP HANA Analytic view as the source ( through Live Data Connection). Here we need to create a Location dimension but do not get any option to do this.

Can you provide your helpful inputs please?

Thanks,

Megha
