I believe the error could also be caused by the data in the Cost column not being able to be converted into the target data type.

I agree with Destiny. If the column was renamed, Power BI Desktop won't be able to find it during data refresh.

I think the possible cause of the error could be that the Cost column was renamed in the data source.

Option B is tempting, but the error message doesn't mention anything about data type conversion problems. Gotta go with A on this one.

Haha, I bet the data source was moved to the 'Trash' folder by mistake. Good thing option D isn't the correct answer!

I agree, option A is the right answer here. Data types and privacy levels don't seem to be the issue based on the error message.

The error message clearly indicates that the 'cost' column is missing from the data source. The most likely cause is that the column was renamed, so option A is the correct answer.
