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.
There are duplicate fields for some dimensions since two different tables have overlapping attributes. You will rename these fields for consistency.
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.
