Thank you for the solution.
I am new to alteryx and learning from different resources within the community for which I would like to thank everyone here.
In solution to challenge #2 I did not get the %b date format in "DateTimeParse(trim(,"'"),"%d-%b-%y")
As per the document it is "mmm" format for %b and "MMM" format for %B but when I am changing it to some other value as per the learning document I am not getting the desired result.
Could anyone please help?
