Hi
If you are using the GETPIVOTDATA function, there is no need to turn
anything on for the formulae using the function to reflect changes in the
pivot table itself.
Refreshing the PT, will refresh the calculations to reflect changes in the
underlying data, and these changes will automatically then reflect in the
cells using your Getpivotdata as part of their formulae.
If your question is about turning on the Getpivotdata icon, then take a look
at Debra Dalgleish's site
