Hello everybody,
i don't find the solution how to sum up quantities of sales by each year, with a time span of three to four years.
e.g. There are sales data from January 1st, 2014 to December 31st, 2017 in the format MMM, D YYYY
Now I want to change the Date format to JJJJ, MM in fact to be able to sum up on this operator.
My result should be the following:
Year, Month sum (Year, Month)
2014, 01 50 tons
...
2014, 12 45 tons
2015, 01 59 tons
...
2015, 12 41 tons
2016, 01 39 tons
...
2016, 12 20 tons
2017, 01 53 tons
...
2017, 12 32 tons
How can i change my Date Format to achieve this? Is it aso possible to change to a german date format as expected above?
Best regards,
Daniel
