Power BI should provide more accurate and actionable error messages by identifying the actual root cause of a failure instead of displaying generic messages. Today, users may see an error such as, "This may be caused by a capacity or licensing issue," even when the real problem is related to the semantic model, such as invalid relationships, duplicate keys, or data model inconsistencies.
These generic messages often lead users to troubleshoot the wrong area, wasting time investigating licensing, capacity, or service availability when the issue actually lies within the data model.
Power BI could improve the troubleshooting experience by analyzing the failure and presenting more specific guidance. For example, if the error is caused by duplicate keys, invalid relationships, or model validation issues, the message should clearly indicate this and provide recommendations on how to resolve it.
Providing root cause diagnostics would reduce troubleshooting time, improve the user experience, and help both business users and developers identify and fix issues more efficiently.
