Question 1 of 30
A data analyst is working on a Power BI report that pulls data from multiple sources, including an SQL database and an Excel file. During the data refresh process, the analyst encounters an error indicating that a specific column in the Excel file is missing. The analyst needs to ensure that the report continues to function correctly despite this error. Which approach should the analyst take to handle this error effectively?
Implement a conditional column that checks for the existence of the column and provides a default value if it is missing.
Ignore the error and proceed with the refresh, hoping the column will be available later.
Manually edit the Excel file to add the missing column before refreshing the data.
Create a new report that does not rely on the Excel file to avoid future errors.
