My subreport has groupings on Account ID then Invoice No. Within the Account ID I could have several Invoice No's.
For example:
Account 1234
- Invoice 6789
- Invoice 5432
- Invoice 5432
- Invoice 9999
What I want is count of invoices. Using the example I should get a count of 3. There are 3 unique invoice numbers under the account id. I have tried a running total, formulas and summary.
