I recently upgraded to 2018.1 and can no longer seem to append data from a csv file to my data extracts. I get a dialog box that says "XX rows successfully added", but the data does not appear. I have updated the extracts from .tde to .hyper but still no dice.
I was able to do this without problem each month when using earlier versions (and can still do it if I use 10.4). Did something change? Is there a trick to doing it in 2018?
Thinking I need to go back to 10.4 for now.
This problem should be fixed in the next release. Look in the release notes for Issue ID 785027. Sorry for any inconvenience.
