[DAX] Dynamic Format Strings WITHOUT Calculation Groups ?!?

Video by: Reid Havens

Learn how to add Dynamic Format Strings for individual [DAX] measures in Power BI! This technique doesn’t require calculation groups or Tabular Editor either, and can be done entirely inside of Power BI desktop.

Side note, if you aren’t using Tabular Editor as a model developer you should be. It’s a fantastic tool for any intermediate to advanced modeling scenarios, and the only way to add calculation groups (today).

Hiding Measures from [DAX] Intellisense!

Video by: Reid Havens

When creating datasets with build permissions (shared datasets), many of us know to hide fields from the data pane. But did you know you can also "hide" measures from the intellisense list in DAX? In this video learn how to use tabular to configure a table property to hide any measures inside of that table, from any DAX intellisense when writing measures. Further increasing usability when creating shared datasets in the Power BI service!

PLEASE NOTE this is not (officially supported) by Microsoft. But is a relatively safe setting to modify. Just be aware Microsoft doesn't provide support for this. More info below at the tabular editor link

(Livestream Replay) Introducing TMDL for Power BI! - with Mathias Thierbach

ABSTRACT 📄

An early look at the Tabular Model Definition Language (TMDL), soon to be released by Microsoft as a public preview as part of the Tabular Object Model (TOM) libraries. TMDL was first presented at SQLBits in March 2023 and is the first of several new innovations and tools targeting the needs of Power BI Pro Developers.

It consists of new declarative format for tabular models, designed for readability and editability, as well as a standardized folder structure for those files (similar to tabular Editor's "Save-to-folder" format), enabling collaborative workflows. Mathias has implemented TMDL as part of the Power BI Contributor Program. He will present the key aspects of the language as well as its main benefits.
