    LOD expressions not support with MongoDB Connector for BI?

    Kurt Slater

      I've been using the MongoDB Connector for BI for a while now and have recently run into an issue with level of detail (LOD) calculations. When I create an LOD calculation, it shows the following error:

      "Level of detail expressions are not supported by the mongodb datasource ....."

       

      I haven't been able any documentation or notes on this limitation. My understanding of the Mongo connector is that it mimics mySQL, and according to Tableau's documentation LOD expressions are supported by MySQL.  Overview: Level of Detail Expressions

       

      Does anyone have additional insight on this limitation?    I'm using MongoDB v3.6, BI Connector v2.5 and Tableau Desktop 10.5.  

       

      Thanks,
