Crystal Reports : Changing Groups at Run Time

This is neat: Let us suppose we want a report to be Grouped on either Users.UserID or Users.UserTerritory, depending on a Parameter field.

So, provide a simple parameter, {?Group} and let the user set it to "UserID" or "Territory".

Now, within your report, create a formula field called {@Group1} and paste in the following code:

IF {?Group} = "UserID" THEN {USERS.USERID} ELSE
IF {?Group} = "Territory" THEN {USERS.USERTERRITORY}

Now, create your Group in crystal, and use {@Group1} as your Group Field.

This way, the user can select how the report should group itself, affecting all summaries, etc.

Try it!
