Background: I'm working at $VERY-LARGE-COMPANY. I am not a Salesforce Admin, and getting the admins to make any changes requires a lot of lead time and a strong business justification.
I am having trouble creating a report to find certain records - cases where $related-object-1.$field1 has value $value1. When my report runs it is missing a lot of cases I know exist and are visible to me, and I notice that all the returned case records have a similar pattern in case.$field2. I suspect that the custom report type which combines cases and $relasted-object-1 was created with a filter on case.$field2.
How can I find out for sure, without talking to a (very busy and overworked) administrator?
