This calculation is applied uniformly. The Total line would divide 300/7 and will return 42.86.

Upgrading Power BI Desktop Models to Tabular

One great feature of Microsoft BI has been the continuum from personal BI to organizational BI. For example, a business user can start small with an Excel Power Pivot model which IT can restore at some point to a scalable Tabular model.

ADOMD.NET Connection Pooling

The focus should be on centralizing data management and improving…
