Bug description:
Datamart export:
When doing datamart exports with lots of data elements I have noticed that
despite the message in UI that says "Export process finished", in the
background the process stops with the WARN message "Cannot crosstabulate since
the number of data elements exceeded maximum columns: XXX". So while UI says
everything is fine, nothing actually gets exported to datamart.
We need feedback to the user and a message that says what the limit is. I also
suggest we do not allow more than the limit number of data elements or
indicators to be selected in the selection box, if that is possible. Right now
I noticed the problem, but I still don't know what the limit is or have any
idea of how many DE I have selected (I am not counting hundreds of data
elements....), so its really hard to do the export.
