  The SAP error message OM481 indicates that an update schema (in the context of SAP's configuration for controlling the update process of data) cannot be deleted because it is still assigned to one or more objects. This typically occurs in the context of the SAP Controlling (CO) module, particularly when dealing with cost center accounting, internal orders, or other related areas.
