Microsoft Power BI pros share their thoughts on how to reference tables, the pros and cons of vertical visual layouts, map routes and app display problems.

Dynamically referencing tables with a Parameter

Erik Svensen discussed how to reference a column name from one table to another table with the same column name. Currently, this isn’t something supported by Power BI. Working with two tables from AdventureWorks, each with a GeographyKey, Svensen leveraged the TableName parameter to retrieve a unique list of values.

An expression error pops up because the parameter is a text value and not a table with fields. He realized that using the #shared function pulls a list of all tables, functions and parameters in a PBIX file, which in-turn can be made into a table and filter based on parameters. Svensen demoed how to get all the GeographyKey values and then change parameters.
