Hi
I'm a new ignition scada user , I'm trying to create Trends in Easy chart its working in Ignition designer and not working at VISION Client Viewer, its showing current user doesn't have the requested roles and same for Ack also I'm not able to do just showing error popup.
Pretty common problem when using legacy database tools (DB pens in EasyChart) when you haven't enabled Legacy DB permissions in the project properties.
Ideally, you would use tag historian pens on the easy chart, possibly with the wide table pseudo-historian provider. Elsewhere, you'd use parameterized Named Queries instead of regular query bindings or scripted queries.
Open the project properties from the menu in the designer. Look for and enable Legacy DB Permissions in security. For DB pens.
For tag historian pens, you need to look at the security roles you've attached to the tag provider and/or history provider.
