If a report is taking a long time to load before prompting the User for values, it may be trying to pull information in from too many different places. Here's where to look first:

The report is retrieving data from a "xxx 2014.x" Universe. These Universes are frozen, any changes to the underlying forms will not be reflected and the customer should migrate to a Custom Universe.

If a single Query is retrieving data from a number of different types of sources (demographics, assessments, Points of Service, TouchPoints, Caseload, family data, etc.) this can affect speed. It is recommended to split the Query.

Points of Service and Assessment should always have a Query on their own, and should include only Identity data.

If a report contains multiple Queries and is running slowly, you can add a "Query status" report to see which ones are taking a long time to refresh.

Using the "Active Filter" in a Query can sometimes slow a report down.

Do not include more than four TouchPoints in a single Query, this can slow a report down.

Using Combination Queries (Union, Intersect and minus) can slow a report down.
