Nah, privacy levels are usually not the issue here.

Wait, could the file just be moved? Seems too simple.

I think it could also be about the data type issue.

The Cost column was probably renamed in Excel.

I feel like privacy levels usually come into play when combining sources, but I'm not convinced that's the issue here. Option C seems less likely.

I practiced a question similar to this, and I think moving the source file could definitely lead to a problem. Option D sounds plausible.

I'm not entirely sure, but I think if the data type doesn't match, it could also cause errors. Could it be option B?

I remember something about columns being renamed in the source file causing issues like this. Maybe option A is correct?

This seems straightforward to me. The error message is pretty clear - the 'cost' column is missing. I'd start by checking the Excel file to see if the column name has been changed.

Based on the error message, I think the most likely cause is that the 'cost' column was renamed in the data source. That would explain why Power BI can't find it. I'll double-check that first.

I'm a bit confused by this one. I'm not sure if the issue is with the data type, the data source location, or something else. I'll need to read through the options carefully.

Okay, the key here is that the error is specifically about the 'cost' column not being found. That suggests the column name may have changed in the data source.

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.

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

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.
