PowerPivot Measures Lost
We recently had a situation with Excel 2010 where, after creating a number of DAX measures (referred to as Calculated Fields in some versions), the PowerPivot measures were lost i.e. the pivot tables treated them as a normal value field with no option to Edit the measure.
It is not clear why this happened but our first attempt to fix the issue was to close the workbook and reopen it. This didn’t work.
However, when we subsequantly closed the workbook AND the rest of Excel and re opened the file, the measures reappeared in there correct format.
