Thanks for contacting Syncfusion support.
We were unable to reproduce the mentioned the same null exception issue at our end. But, we have tested the shared reportitem expression and it’s rendered the same values in all the row cells (this is the know error) in Tablix report items as shown in below screenshot. So can you please share the issue reproducible RDL file without confidential information to validate the mentioned null exception issue at our end.
For your reference, we have prepared a sample and it can be downloaded from,
I reproduce the issue in the sample below (+RDL file).
About your RDL file, I get the same error (render the same values in all the row cells) but instead it works well in SQL Report Builder.
Another problem about the percentages, I have diagrams (Pie) showing the percentage of each part in SQL Report Builder, but in the browser (ReportViewer), it just show me the total number without percentage. How to fix this too?

Currently, we don’t have support for using aggregate function for reportitems expression in ReportViewer and we have an issue while providing data label format in chart report item at our end. We have logged a feature and defect report on this respectively. So a support incident to track the status of this feature and issue has been created under your account. Please log on to our support website to check for further updates. https://www.syncfusion.com/account/login?ReturnUrl=%2fsupport%2fdirecttrac%2fincidents

Hi there, has there been any progress in support for using aggregate function for reportitems? I also would like to use this to provide running totals per page.

We have not yet provided the support for using aggregate function for report item expression in Report Viewer. We will be providing this support in our 2019 Volume 1 release which may be scheduled to be released in month of February 2018.
