Hi,
Are you trying to run the report via code? If so, you can only do that using the UI objects as there is not DIAPI for reporting.
You first need to activate the menu item for the report:
connect.SboApp.ActivateMenuItem("13058");
Once you've done that, you can get the active form which will be your criteria window, use the UIAPI to set your criteria and run the report by getting the OK button object and calling the Click method.
