An introduction to using snapshots in SQL Server Reporting Services, including an explanation of the differences between a “Report Execution Snapshot” and a “Report History Snapshot.” 1. Most reports typically are executed on demand – i.e., the query in the dataset runs and the report is displayed at the time the report is requested by the user. If you have a long-running query that cannot be tuned further, one option you might look into is caching.This is the default in “Processing Options” within Report Manager (accessed via the “Manage” menu option). With this method, the first user that executes the report will wait for the report to render.(Alternatively, if the data rarely changes you could control when it’s created by using the Apply button option.The Apply button is also useful for generating the first snapshot for testing.) There’s one more really important thing to be aware of.So, basically you want to make sure you set the schedule associated to the purpose you’re trying to accomplish.Usually it’s just one or the other, but it could be both depending on the requirements.
For instance, if the default is always “current fiscal period” that continually changes, you can make this happen with an intermediary hidden parameter – it might just take a bit of extra time to think up a good solution.Many of us who have to develop a Reporting Services (SSRS) application come across various problems, hurdles or 'gotchas' that cause much head-scratching.We've never seen, elsewhere, the ten most common SSRS problems ever listed, let alone their solution, but then along came Ryan with both.Help is now at hand for anyone wrestling with Reporting Services. In every business there are several different groups of report users, from chief executives, to business analysts, to operational staff, who all need access to reliable and current data in order to track overall business performance, investigate the effectiveness of individual business functions, or simply for ad-hoc day-to-day reporting.In most organizations, at least some attempt has been made to meet these reporting needs.

If you are familiar with subscriptions in SSRS, these will sound familiar. If you aren’t using a data source with the ID and Password stored (so that data level security is a non-issue when it runs), you’ll get the message “Credentials used to run this report are not stored.” Create a separate shared data source that has a name such as “MCGarden Center DW_Stored Creds” so you know at a glance it’s using a specific ID and Password as opposed to Windows Authentication (assuming Windows auth is your default). Another prerequisite for using snapshots is that all parameters need a default value defined.
