Because we've moved to the Salesforce Analytics API, we have a few restrictions that are driven by Salesforce limitations.  See the following list of Analytics API limititations:

  1. Get up to 200 reports that you most recently viewed.
  2. Get results for the first 2000 report rows, which includes detailed record data. You can narrow results using filters to get the most useful bits.
  3. Add up to 20 custom field filters when you run a report. The number includes existing custom field filters saved to the source report.
  4. Send requests for reports that have up to 100 fields as columns.
  5. Access results of an asynchronous report run any number of times within a 24-hour rolling period.
  6. When filtering data, cross filters and standard report filters are not available.
