  The SAP error message ESH_OM_OBJ_MODEL_REP139 indicates that there is an issue with the navigation path in the context of the Enterprise Search (ESH) Object Model. Specifically, the error message states that the "Key of navigation path step is not fully specified." This typically means that the system is expecting a complete key for a navigation path step, but it is missing some required components.
