Set Names Should Not Include Special Characters

​What are the limitations in naming sets? Because set names are stored in the database and these names are used to retrieve information about the sets, special characters like ‘&’, ‘%’, ‘-‘, ‘()’, single quotes (‘) and double quotes (“) should not be used. These characters have special meaning in the programming languages used to develop reports. When these special characters are used, the reports will often fail. Please take note the next time you are creating a new set in the system.
