Beginning DAX with Power BI – Book
The second CALCULATE attempts to derive a total value for sales for each day. This daily total is used with the first value to derive a percentage for each product/day combination. Once again, the way the calculation has been written, you do not see these intermediate values. How can you sure the values used in the DIVIDE calculation are the values you think they should be?
The easiest way to break this calculation down is to create a separate observable entity for each of the CALCULATE functions. This can take the form of several new calculated columns, or you can use variables and control which variable is returned via the RETURN statement.
