The SAP error message SV789, which states "Display and Maintenance of view/table & not allowed," typically occurs when a user attempts to access or modify a database view or table for which they do not have the necessary authorizations or when the view/table is not intended for direct maintenance. Causes: Authorization Issues: The user does not have the required authorizations to display or maintain the specified view or table. Technical Restrictions: The view or table may be designed as a read-only object, meaning it cannot be modified directly.

Solutions: Check Authorizations: Verify that the user has the necessary authorizations to access the view or table.
