I have a few Saved Reports, based on Sales By Rep, that have worked flawlessly since I first created them last December.

For the past few days, we are unable to get them to run.

I have tracked it down to a custom Transaction Column Field called "Sales Type". That field is a List/Record type based on a custom List of four (4) Sales Types:
[LIST]
[*]New Sale
[*]Trial Sale
[*]Conversion Sale
[*]Renewal Sale
[/LIST]

When I remove that field from the report columns, the reports run as expected. When I add it back in, I get a timeout/failed response. It seems that this field is causing the report to return multiple rows of each transaction - dozens or even hundreds. Even if I filter down to a single day, the results are exceeding the 25,000 record limit and timing out.
