User Defined Format

For example, you define a parameter of Date type and the following formats can be recognized: M/d/yy; MMM d, yyyy; MMMM d, yyyy; EEEE, MMMM d, yyyy. But if you want to enter a value like 1996.July.10, you should specify the user defined format as yyyy.MMMM.d. But remember it is the entering format, not the display format. To customize the display format, go to its Format property in Report Inspector, enter your customized display format as yyyy.MMMM.d. Then when you enter 1996.July.10, it will be displayed as 1996.July.10.

For details about how to define a user format for different types of parameters, refer to User defined format for parameters.

Note: The letters standing for year, month, and so on are case sensitive and should follow the standard of Java java.text.DateFormat, java.text.NumberFormat, and so on.
