Prompts in workspaces in Cognos Workspace
If a workspace includes reports and report parts from the same model, prompts automatically filter the appropriate data item in all the widgets in the dashboard. For example, a prompt filters on Product Line. Any widget in the dashboard that includes the Product Line data item is filtered when you select a value from this prompt control. If you do not want a prompt to control a widget in the dashboard, you can disable communication between the two widgets.
If a dashboard includes prompted reports or report parts from different models, ensure that the prompts use the same parameter names. For example, a year prompt should use the same parameter p_Years in reports from both models. Otherwise, the prompt control is unable to control reports from another package.
