There are a few workarounds we can try to employ to get you the results you are looking for:
  1. Rebuild the query or report to involve fewer queries, criteria, or report columns
  2. Do not navigate away from the screen when you're previewing a query or running a report to screen. The process still runs in the background and has to complete. Navigating away or clicking your back button does NOT cancel the request.
  3. If there are a large number of results expected in the report, schedule it to run overnight
  4. Add criteria to the query to help segment the results into smaller, more manageable results
  5. Contact Support and reference this article.
