I just started my level 3 training and I'm having issues. I've tried almost every combination and I cannot map time for some reason. Does anyone know why? I'm sure it's something simple.
Your file and mapping seem to be correct (couldn't find anything wrong in the screenshots), try the following things:
1- Try selecting Y-M as the period format
2- Try checking the format of your source file column is text
3- Try custom format YY-MMM
Hope this helps!
