In the Project Editor, select System | Reports. The Reports dialog box will display:
For each report, in the Cluster Name field, select the cluster that will run the report. If there is only one cluster defined in the project, you can leave this field blank. The reports will default to the defined cluster.
If the project has multiple clusters, and you do not select a cluster in this dialog, then CitectSCADA considers the report to run on defined clusters.
