Data Set 1
| Row | City | Amount |
| 1 | Chicago | 47 |
| 2 | Dallas | 43 |
| 3 | Dallas | 35 |
| 4 | NYC | 25 |
| 5 | Detroit | 32 |
| 6 | SFO | 24 |
Data Set 2
| Row | City | Amount |
| 1 | NYC | 25 |
| 2 | NYC | 26 |
| 3 | NYC | 16 |
I have a requirement not to display any data if the complete data set in the City column has NYC along with other cities.
For example in the data set 1, I do not want to display any data(or display an Custom Error Message) on the report because it has NYC along with other cities. Where as in Example data set 2, I want to display all 3 rows because NYC is the only city in the data set.
FYI -
In my report I have data displayed on multiple groups and I am using command based report.
