How to achieve conditional page breaks in SSRS 2016

With RB (and sufficient privilege), users can save reports straight to the Report Manager environment. At that point, they're deployed. But if you want to have them save those reports to a Dev/Test box, and want to push them live, there's a few options.

One easy option is to move reports into a known folder 'For Deployment'. You can then have a script which grabs the RDL for reports in here and uploads them to the proper server. You'll probably want to make sure the data sources are mapped appropriately as this method can annoyingly lose references. You can use rs.exe for your scripts, or just use the web references. PowerShell can be very useful here, as it happily talks WebService, and you can schedule PowerShell scripts using SQL Agent jobs.

Ini. My first thought here is that you could use a List control to iterate across Districts. SQL Server MVP Jes Borland has a great intorductory post on Lists here: http://jesborland.wordpress.com/2010/11/17/the-power-of-reporting-services-%E2%80%93-lists/

Inside the list control will be a rectangle. By setting the Page properties of that rectangle, you can create yours tabs for each District, dynamically setting the Page Name property to an expression that returns the District.

You could configure your dataset (ideally, a stored procedure) to take the Region as a parameter and then you can run this ONE report for each of your Regions and they will all work the same and keep you from having to create multiple copies of the same object.

Assuming I understood your question correctly, this should get you moving in the right direction.
