Hello,
We seem to always get this error message when we work on Visio. Somehow Visio loses its link with Excel. This always occurr when we create pivot diagrams in Visio and then close Visio to make edits/adjustments in the Excel data. This error will show up even when there were no changes in the Excel data. It is annoying as we cannot refresh/update the pivot diagrams. It causes us the recreate all the pivot diagrams again.
Any help would be greatly appreciated.
Thanks.
