Dear,
I have a data source with a number of colunms which are coming from an external data source and the second part of the data sources is filled with formula's.
in my pivot table I use 2 fields for filtering, these fields are coming from calculated colums.
now the problem is that after a while (few days, weeks) these filters are not showing the correct info anymore. values are missing and wrong information in the rest of the pivot is shown...
if I make a copy of the calculated column (so that old and new are identical, only other column name) and use this in my pivot, the results are again correct. but after a while, I have the same problem again... I'm using Excel 2010
I can provide the excel file if needed.
wkr,
Filip
