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 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.
