I kind of need an answer to this posting, even if it is to say you can't do that. This is a high priority issue for the deployment of this report. Basically I have 3 parms. Param A and B are the date ranges of the report which the user should be able to change. Parm C is a UserId which is being passed in the URL and is used in the query for the report to look up what customers this user is allowed to view and return from the query. The user of the report should not be allowed to change this parm because we do not want them to see other reps customers. Therefore parm C should either not be able to be changed or hidden. Is this possible? I have Parm C setup with no prompt, do not allow null, do not allow blank, a default value of 0. When we run the report parm C shows up the Report Parameters menu and you can change its value.
