I was a previous user of KReporter, and lost functionality a while back during an upgrade. When I went to check it out, I saw the developers were creating their own CRM: SpiceCRM and didn’t seem to be focused on SuiteCRM compatibility anymore.
I’ve been happy with using the SuiteCRM Reporting tool that was added, in combination with a product called PHP Report Maker. The latter is generic (not CRM aware) but I love what I can do with it, including the graphs. I opted for the paid version. I have version 9, but will be upgrading to 10 when I upgrade to 7.10.X (lts).
I simply run the two side by side and pint PHP Report Maker to my SuiteCRM database. I preferred being able to write my own SQL anyhow. I know this solution won’t be for everyone, but I love it.
