I've made a report on two views.
And it runs well https://gyazo.com/e93143619a9b1bf705cdfe3d420acaa5
But when I add KPI Functionality https://gyazo.com/f91bdabac0a5f068259949792c93964d
there is error on run https://gyazo.com/d63a3f48202b796db06a0a0fd6fd503b
And NPE exception at server log.
Unfortunately none of your attachments or links have come through. Furthermore, for any issues
related to system errors, it is better to send these to email@example.com and include all your system
information, screenshots, and your YF log files zipped up.
Thank you very much,
