additional info:
if your report using a Stored Procedure (SP) or View with parameter to collect some data then you need to modify the SP/View it self.
After you finish then you need to verify your report
here is the steps:
*To Check if your report using SP or View
- click on Database menu
- click on 'Set Datasource Location...'
here you'll see your ODBC name and the SP (or View)
- expand your SP/View, to see the real SP/View name
till here you can open and add parameters on your SP
*To verify your report
- click on menu 'Database'
- click on 'Verify Database'
in this stage CR will sync with the SP/View (if there are some changes on fields / params, etc.)
hope it help.
