Welcome to Episode 10 of my Power BI Best Practices Series. In today’s episode, I will show you how to include a report support tab in your Power BI report. This tab helps your users see where the data comes from. Also, here you can include your contact information, so the users of your report will know how to reach you if they have questions.

When converting Oracle database code to Microsoft SQL Server, I often face the problem of correctly mapping Oracle data types to SQL Server data types. I regularly use SQL Server Migration Assistant (SSMA) to automate Oracle database code conversion to SQL Server. However, SSMA’s default data type mapping for Oracle procedure and function parameters uses the maximum possible size for each specific data type to prevent data loss. This approach causes unintended consequences with application code.

Drillthrough pages allow for your users to navigate to different pages within your report to expore the details of the visuals that they choose. For example, you can create a drillthrough filter in Power BI based on the specific entity.
Managing customer’s SQL Server applications, we discovered a significant performance decrease related to query execution time. We figured out that the reason for that was the execution of a script, which checks the existence of database objects before updating them. Initially, the developers created this script to emulate the behavior of the CREATE OR REPLACE statement from many other database platforms.
We solved the performance issue by replacing the original script with a new code snippet.
In our second Amazon QuickSight introduction blog post we will go through the basic steps in building a dashboard. These steps include importing a CSV data set, creating calculated fields and data analysis.
