When splitting my Power BI into a dataset with N thin reports (dataset clients), and I change a column or measure name, all N reports will break because they reference dataset's column/measure by name. The Measures I build *should have unique IDs* - so if I change the name, as long as the original measure is the one used, it should just *updated on the reports themselves*. For now, the only "solution" available is to open all N reports one by one and *rebuild them manually*. Very painful! More dangerous and tricky is opening pbix like @parra described here: Modifying the Layout file that is embedded in a pbix file https://community.powerbi.com/t5/Desktop/Modifying-the-Layout-file-that-is-embedded-in-a-pbix-file/m-p/1616614/highlight/true#M652387 More details about this problem were exposed by @TO_CB and discussed on this community forum post https://community.powerbi.com/t5/Desktop/Modifying-Layout-file-inside-pbix/m-p/2095628
