OfficeWriter Reporting Services Integration is available in both OfficeWriter Enterprise Edition and OfficeWriter Standard Edition. When you select a feature that is available in the Enterprise Edition only, the Enterprise Feature dialog will open. The dialog allows you to disable the warning and/or hide Enterprise features. Both the Enterprise Feature dialog and Enterprise features can also be disabled through registry settings.
You can also disable Enterprise features through The OfficeWriter Designer for Excel. Go to Help > Settings and select/de-select Show Enterprise Features.
OfficeWriter Editions lists the Reporting Services Integration features available in each edition.
