I have a date field, it's format in DB like this 'mm/dd/yyyy'. How do I group by by YEAR -Month in Report Studio?
You should create a calculation that is returning just the month and year, from your date item.
Use the Extract(datePart, [dateItem]) function to get the pieces and then concatenate them together, in a format you desire.
Then Use that calculated Year-Month item in the report and group on it.
Thank you! It works! :D
