After testing for a while reporting widget, I’m really impressed, I must say… But watching at data table in per-device mode, one thing came into my mind:
The table is sorted in a growing pin number order. Ok, that’s not a problem at all…
But there are three columns: A data value, a timestamp and a pin number.
And my question: Wouldn’t it be more logical to order those in a different way:
The timestamp, the pin number, and finally the pin value?

I don’t know. Is it? I thought if you do export to some 3-d party does that matter?
By the way I just made some draft doc for it - https://github.com/blynkkk/blynkkk.github.io/blob/master/mobile/report.md
BDP ? 
Sorry, what is that? Can’t google 
.
That’s my short of famous “Best Design Practice” 
Good. Cause what I googled was Big Dick Problems 
.
Regarding order - I really don’t know. What is the usage? I thought you just put it to excel and view as the graph. So why order is important here?
God, no way! But could be other shorts as well… OK, let’s stop it as it might get “censored” at some point 
As for the order: Well, sure it is not a big deal… you can choose columns and reorder them, or leave as they are - they are always usable. BUT… that is the way I would expect them to appear. And that is the way it seems to be most common order - at first timestamp, second group, last data.
(If only the forum would allow to create some form of voting…)
Edit: even default graph creator defaults the first column as an X axis… Am I right? (or not? - don’t remember actually 
)
I’m with you and would make the time first. As X axis generally cames first.
Thanks ! Now I need to figure out the errors appearing when creating reports… They appeared after update. Server
0.38.2.
What errors?
Error after submitting report. I will try to remove and recreate report settings later. Will let you know ASAP
Yes, Local 0.38.2… Here’s blynk.log (from server startup till the unsuccessful report generation.)
Note that “per pin” reports were successfully generated, but per device and the newest “REPORT” failed with errors.
One more note: Click DATA SOURCE --> Project Devices Now UNSELECT some devices and GO BACK. Enter again Project Devices, and… Yes, they are still ALL selected 
OK, here’s the LOG:

@marvin7 wrong logging on the server =(. Not enough info to solve the issue. Could you please re-run your report with this build https://github.com/blynkkk/blynk-server/releases/download/v0.38.2/server-0.38.3-SNAPSHOT.jar and post logs again (stacktrace for the error would be enough)
Ok, give me few minutes:
IS it java 8 build??
No. Do you need java8?
To run on my hardware? - YES…
