Here's an example, if you need help building the actual view:
You can set the year start as July in your data window, as described here:
From link above:
Fiscal Year Start
This is another property of date fields. Fiscal Year Start provides a list of the months from which you can select the one that starts your fiscal year.
To set the fiscal year, right-click the field in the data window, and select Default Properties > Fiscal Year Start, and then select the month.
If this doesn't help resolve your issue, then please mock up an example using the sample Superstore data provided with Tableau, and post a packaged workbook (.twbx) with the view set up as close as you can get it--then, we can help guide you toward a solution.
Worked perfectly! Thanks Matthew
No problem, glad to help!
