Private Dashboard in the section My Dashboards can only be exported, renamed or deleted by the user who created them.
When another user, even an Admin with all Authorizations and Privileges, tries to export/delete the DASH object the following error is displayed:
U00004509 Access violation: User: 'USER/GROUP' Object: 'MY.DASH.123' Access: 'W' Reason: No right found in object.
Release : 12.2 and higher
Component : AUTOMIC WEB INTERFACE
The reason for this behavior is that when the Dashboard is created, specific Authorizations on the objects are created for the user that created the object. These overrule the Admin users Authorizations.
This is the expected behavior.
If for any reason the Dashboard needs to be renamed/deleted - there are two options
Incase the user(owner) is no longer part of the organization/team - Upon deletion of the user(owner) object - The Object level authorizations are automatically removed and the Private dashboards become Public dashboards which then allows for rename/delete operations.
