  This error occurs when a user tries to select multiple rule sets simultaneously in a context where only one rule set selection is allowed. Typically, this happens in SAP Workflow or Business Rule Framework plus (BRFplus) applications where the UI or processing logic expects a single rule set to be selected for further processing, but the user has selected more than one.
