I have a dataset that I replace regularly and would like a timestamp on the report to show when this file was last created.
The source comes from a sharepoint folder and looks like this on import:
For some files, it reads the 'Date Modified' and 'Date Created' columns correctly. Unfortunately it doesn't read it correctly for any of the files I need it to read from - when I change the type to text or to any (see below) it still doesn't work.
If I click on the error it tells me this:
So the data is there, but it still tries to read it as DateTime value and not as text/any value even after changing its type.
Can someone help please?
Solved! Go to Solution.
Hi @Erf19
If "Type Detection" is checked by default, power bi will change the column type automatically when data is imported.
Please uncheck this selection, then close your file and reopen a new file.

It sounds like the values are being parsed in the day/month/year format, which would mean that it fails when the month is out of range. To fix this, choose the bottom "Use locale" option when changing column type.
