Reproducing the Issue

  1. Go to the work center Business Analytics.
  2. Open your report from the Design Reports view, or your data source from the Design Data Sources view.
  3. Start the report or data source.

You see the error messages.


One cell in reporting supports up to 17 digits (for interger values). In your case, a key figure contains a value with more than 17 digits which causes the error.

This can happen where the selection is not restricted, and some key figure values therefore contain very large values.


Please put a selection in place before you run the report or data source. This will ensure that the values are not too large (under 17 digits).
