Hi Mike, Andrej,
Thanks for the response.
Further analyses indicates that the most recent version of the Pivot Table Widget (created by ITvisors) does support decimal values.
I missed this one. Good thing that André contacted me directly. The old version, which i published while working for Synobsys, does not support Decimal. And it is no longer maintained.
Please use the version I published recently under ITvisors, which does support Decimal and is ready for Mx7
The Pivot Table Widget does not support decimal values. I would suggest rounding your Usage values to integers (perhaps in a different attribute) for use in the Pivot Table Widget.
Hope that helps,
