Correct Answer: To create reports that compare the sales from a month this year to the sales from the same month last year, you need to set up a date interval in Dynamics 365 Finance and Operations by following these steps: 1. Navigate to General ledger > Ledger setup > Date intervals. 2. Click New. 3. In the Date Interval Code field, type a code such as CurrMth PY. 4. In the Description field, type a description such as Current Month Previous Year. 5. In the Interval Start section, select Month in the From date period type field. 6. In the From date start/end, select Start. 7. In the From date +/- field, type -1 for -1 year (previous year). 8. In the From date adjustment unit field, select Year. 9. In the Interval End section, select Month in the From date period type field. 10. In the From date start/end, select End. 11. In the To date +/- field, type -1 for -1 year (previous year). 12. Click Save to save the date interval. Ensure that the Interval End section mirrors similar settings for the end date period type but specifies that it's the end of the interval and includes the year adjustment to accurately capture the previous year's interval.
