Data clean up

The business users have informed you that all valid transactions have an Invoice No. You need to remove transactions with empty invoice values.

We do not recommend doing so, but if you lost progress you can load the solution workbook of the previous exercise 1_1_data_source_solution.twbx from the Workbooks folder.
