PL-900 Practice Question: A user sees the exhibit error when opening a…
Exhibit
Refer to the exhibit. Error: "The data source for the report has been removed or changed. Please refresh the report to get the latest data."
A user sees the exhibit error when opening a Power BI report in the service. What is the most likely cause?
⚠ Common exam trap
A common mix-up: candidates confuse a data source connection modification error with a gateway offline error, because both can prevent data loading, but the gateway error is specific to on-premises connectivity while the connection modification error occurs even with cloud data sources.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
The data source connection in the service was modified
The error shown in the exhibit is a typical 'Couldn't load the data for this visual' message that occurs when the data source connection defined in the Power BI service has been changed (e.g., server name, database name, or authentication method) but the report's underlying dataset still references the old connection. This mismatch prevents the service from retrieving data, even if the gateway is online and credentials are valid. Option D is correct because modifying the data source connection in the service without updating the dataset's connection string breaks the data retrieval pipeline.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
The scheduled refresh failed due to credentials
Why it's wrong here
Credential failure would show a specific credential error.
- ✗
The on-premises data gateway is offline
Why it's wrong here
Gateway offline would show a gateway error, not this message.
- ✗
The dataset was deleted from the workspace
Why it's wrong here
If deleted, the report would not open at all.
- ✓
The data source connection in the service was modified
Why this is correct
This error indicates the dataset cannot find the data source.
