I have a main report that has two parameters (RptMonth, Reports). RptMonth which the user selects from a calendar, and Reports which is a dropdown list. Produces main report correctly.

Parameter settings - Name=ID, datatype=Integer, parameter visibility=hidden. Get values from query=Dataset1, value field=ID, label field=KPI. Using always refresh. This is all configured in the main report. In the detail report I have one parameter named ID, type Integer, visibility=hidden. Security for both reports use embedded connection, type SQL server.

Hi, Based on your description, i tried it in my SSRS 2008 environment, everything works fine. However, 1. Since the parameter is hidden, why do you set its values from one dataset? 2. Does the error message say which parameter is read only? 3. Open the reporting services error log files to see if there is some details about this error. If the above did not help you out this issue, you can send the rdl files to me through the email sqltnsp AT microsoft DOT com, i will give you a feedback once i get them. thanks, Jerry
