I was playing around with reports and I used one of the standard reports Contacts & Accounts. It generated results.
I then tried going into custom report types and did the same thing. I selected Contact as the primary object and then Account as the secondary. After saving it, I selected this report type when creating the report but it generated 0 rows.
Here is how the custom report went.
Even if I changed it to the second option, the report would still have no rows returned.
And here is what the resulting custom report looks like. I added no filters.
And here is the resulting rows if I just selected the standard Contacts & Accounts report.
Any suggestions as to why this might happen? I thought the custom report had the same logic as the standard report...
UPDATE:
Here are the "folders" that I see on the custom report type.
And here are the "folders" that I see on the standard Contacts & Accounts report (there might be some additional things that my org customized that might not appear on some standard reports...).
