When using Power BI Copilot, you may encounter a warning message stating that Copilot analyzed only part of the model due to its size.
This warning occurs because Power BI Copilot creates an index of text column values in your semantic model to better answer your questions.
The indexing process has a limit on the number of text values that can be indexed, and when this limit is reached, the warning appears.
For more information on the indexing process, it is recommended to read the docs.
Another common warning message,
Copilot is currently syncing with the data model, is displayed during the indexing process.
