These classes include detailed descriptions, identification rules, and dependent relationships, forming the foundational data model for enterprise asset management. Show full answer Show less To access these capabilities, customers must install the Expanded Model and Asset Classes application from the ServiceNow Store. The enterprise model classes and asset classes are organized in hierarchies where child classes inherit parent attributes. Relationships between models and assets are managed through model categories. ## Supported Enterprise Model Classes The application extends the base **Product model \[cmdbmodel\]** class into key enterprise model classes: * **Enterprise good model \[snentmodel\]**: The primary model class for enterprise assets, parent to various industry-specific child classes. * **Firmware model \[snentfirmwaremodel\]** and Discovered firmware model \[snentdiscovfirmwaremodel\]. Industry-specific child classes under the Enterprise good model include: * Medical model and Medical device model for healthcare equipment and devices, with special handling for Product Instance Identifier (PID) generation to link assets and configuration items. * Medical drug model for pharmaceuticals. * Facility, Transportation, Industrial, Retail, Tactical equipment, Construction, Wearable, Multimedia production equipment, System and smart card, and Payment card models, each classifying models in their respective sectors. **Important notes for customers:** * Starting with the Zurich release, the classification column in the Enterprise good model is deprecated; classification data now resides in the Product model table. * Consumable models are not classified through the base CMDB consumable class; instead, models can be designated as consumable by setting the Model type field on enterprise model records. * Upgrading to Expanded Model and Asset Classes version 1.2.0 or later may require manual reclassification of existing medical device models. ## Supported Enterprise Asset Classes The Enterprise Asset Management application extends the base **Base asset \[almbase\]** class with the **Enterprise asset \[snentasset\]** class, which serves as the parent for several industry-specific asset classes: * Medical asset, Facility asset, Transportation asset, Industrial asset, Retail asset, Tactical equipment asset, Construction asset, Wearable asset, Multimedia production equipment asset, and System and smart card asset classes. These classes classify physical enterprise assets across various industries, enabling precise categorization and management. **Additional class:** The Linear asset \[sneamlinearasset\] class and its child Linear segment \[sneamlinearsegment\] class support classification of linear assets and their segments, useful for managing assets like pipelines or roadways. ## Practical Benefits for ServiceNow Customers * Provides a comprehensive and extensible data model tailored for managing diverse enterprise assets across industries. * Enables inheritance of attributes and structured classification, improving asset tracking and lifecycle management. * Supports unique asset identification through PID configurations, especially critical for regulated industries such as medical devices. * Facilitates integration with CMDB and configuration management processes by aligning asset and model data. * Allows customization and extension through industry-specific classes, supporting customer-specific asset management needs. The Enterprise Asset Management application supports enterprise model and asset classes that extend base classes within the Configuration Management Database (CMDB) class hierarchy. These extensions include class descriptions, identification rules, and dependent relationships. To access enterprise model and asset classes in the Enterprise Asset Management application, you must install the Expanded Model and Asset Classes application from the ServiceNow® Store. For more information on this application, see [Expanded Model and Asset Classes](https://www.servicenow.com/docs/SdMxc3p6hYAWsVcZjPOZ3Q "The Expanded Model and Asset Classes application adds model and asset classes that extend base classes within the Configuration Management Database (CMDB) class hierarchy. These extensions include class descriptions, identification rules, identifier entries, and dependent relationships. The application also adds model categories and API categories."). Enterprise model and asset classes form the structural backbone of the Enterprise Asset Management data model. These classes are organized into class hierarchies, in which child classes extend their parent classes and inherit all parent attributes. The Enterprise Asset Management application establishes relationships between enterprise model classes and enterprise asset classes through model categories. For more information on model categories, see [Model categories](https://www.servicenow.com/docs/RnMb5ZVqZn2w9pWX4GOucQ "Model categories define the relationships between enterprise model classes, enterprise asset classes, and Configuration Management Database (CMDB) CI classes in Enterprise Asset Management. Model categories connect every enterprise asset to the correct model class, asset class, and CI class."). ## Supported enterprise model classes {#enterprise-model-asset-classes__section_xfd_hy5_25b} The Enterprise Asset Management application supports the Enterprise good model \[sn_ent_model\] class, Firmware model \[sn_ent_firmware_model\] class, and Discovered firmware model \[sn_ent_discov_firmware_model\] class, which extend the base Product model \[cmdb_model\] class. The Enterprise good model \[sn_ent_model\] class is the primary model class for enterprise assets in the Enterprise Asset Management application. It is also the parent class of the following industry-specific enterprise model child classes:{#enterprise-model-asset-classes__table_o2v_sy5_25b__entry__2} | Enterprise good model child class | Description | |-|-| | Medical model \[sn_ent_medical_model\] | Classifies medical-based enterprise models, such as ER Medical Cart Kit and ECG Electrodes. | | Medical device model \[sn_ent_medical_device_model\] | Classifies medical device-based enterprise models, such as Blood Pressure Monitor and MRI Patient Table. Note: When you upgrade to version 1.2.0 or later of the Expanded Model and Asset Classes application, the application automatically runs the Update medical device category fix script to associate the Medical Device model \[sn_ent_medical_device_model\] class with the existing Medical device model category. However, you may need to manually reclassify existing enterprise models under the Medical device model category from the Medical model \[sn_ent_medical_model\] class to the Medical Device model \[sn_ent_medical_device_model\] class. Refer to [KB1182183](https://support.servicenow.com/nav_to.do?uri=/kb?id=kb_article_view&sysparm_article=KB1182183) for detailed instructions. Product Instance Identifier (PID) which is a unique and common identifier that links the asset, CI, and IBI classes is generated for the assets of Medical Device model category. PID is generated based on the PID configurations applicable for the Medical Device model category. The Product Instance Identifier Configurations \[product_instance_identifier_configuration\] table stores the PID configurations. By default, the following configurations are available: * PID - Serial number that includes a parameter defined based on the Serial number field of the Asset \[alm_asset\] table. * PID - Parent that includes parameters defined based on the Parent and Model Component ID fields of the Asset \[alm_asset\] table. {#enterprise-model-asset-classes__ul_inn_x3h_vzb} When many PID configurations are associated with the Medical Device model category, the configuration with the highest priority is considered first during the generation of the PID. The PID - Serial number configuration is mostly given the highest priority. | | Medical drug model \[sn_ent_drug_model\] | Classifies medical drug-based enterprise models, such as Amoxicillin and Prilosec. | | Facility model \[sn_ent_facility_model\] | Classifies facility-based enterprise models, such as HVAC Split System and Wire Shelf. | | Transportation model \[sn_ent_transportation_model\] | Classifies transportation-based enterprise models, such as Disc Brake Rotor Front and Fuel Cell Car. | | Industrial model \[sn_ent_industrial_model\] | Classifies industrial-based enterprise models, such as CNC Milling Machine and Laser Cutting Machine. | | Retail model \[sn_ent_retail_model\] | Classifies retail-based enterprise models, such as Retail Counter Scale and 80mm Thermal Receipt Printer. | | Tactical equipment model \[sn_ent_tactical_model\] | Classifies tactical equipment-based enterprise models, such as K19 Plate Carrier and Triple Mag Pouch. | | Construction model \[sn_ent_construction_model\] | Classifies construction-based enterprise models, such as Excavator and Hex Breaker Hammer Kit. | | Wearable model \[sn_ent_wearable_model\] | Classifies wearable asset-based enterprise models, such as N95 Respirator and High-vis Safety Vest. | | Multimedia production equipment model \[sn_ent_mm_prod_equip_model\] | Classifies multimedia production equipment-based enterprise models, such as Production Camera and Modular Broadcast Console. | | System and smart card model \[sn_ent_system_smart_card_model\] | Classifies system card- and smart card-based enterprise models, such as Smart Card and Magnetic Stripe Card. | | Payment card model \[sn_ent_payment_card_model\] | Classifies payment card-based enterprise models, such as Debit Card and Credit Card. | [Table 1. Enterprise good model child classes] {#enterprise-model-asset-classes__table_o2v_sy5_25b} Important: Starting with the Zurich release, the Classification (classification) column of the Enterprise good model \[sn_ent_model\] table has been deprecated and renamed as Classification (deprecated). Data from the deprecated column is now available in the Classification (classification_code) column of the Product model \[cmdb_model\] table. Note: The Enterprise Asset Management application does not classify consumable models through the Consumable model \[cmdb_consumable_product_model\] class that is available in the base CMDB class hierarchy. Instead, you can manually designate any enterprise model in any model category as consumable by setting the Model type field to Consumable on the corresponding enterprise model record. ## Supported enterprise asset classes {#enterprise-model-asset-classes__section_jw5_dfv_25b} The Enterprise Asset Management application supports the Enterprise asset \[sn_ent_asset\] class, which extends the Base asset \[alm_base\] class. The Enterprise asset \[sn_ent_asset\] class is the parent class of the following industry-specific enterprise asset child classes:{#enterprise-model-asset-classes__table_kw5_dfv_25b__entry__2} | Enterprise asset child class | Description | |-|-| | Medical asset \[sn_ent_medical_asset\] | Classifies medical-based enterprise assets, such as hospital beds and X-ray machines. | | Facility asset \[sn_ent_facility_asset\] | Classifies facility-based enterprise assets, such as coffee makers and HVAC systems. | | Transportation asset \[sn_ent_transportation_asset\] | Classifies transportation-based enterprise assets, such as airplanes and brake pads. | | Industrial asset \[sn_ent_industrial_asset\] | Classifies industrial-based enterprise assets, such as forklifts and casting machines. | | Retail asset \[sn_ent_retail_asset\] | Classifies retail-based enterprise assets, such as display cases and clothing racks. | | Tactical equipment asset \[sn_ent_tactical_asset\] | Classifies tactical equipment-based enterprise assets, such as hydration carriers and tactical plate carriers. | | Construction asset \[sn_ent_construction_asset\] | Classifies construction-based enterprise assets, such as sledgehammers and hand saws. | | Wearable asset \[sn_ent_wearable_asset\] | Classifies wearable enterprise assets, such as helmets and uniforms. | | Multimedia production equipment asset \[sn_ent_mm_prod_equip_asset\] | Classifies multimedia production equipment, such as video mixers and broadcast sync generators. | | System and smart card asset \[sn_ent_sys_smart_card_asset\] | Classifies system cards and smart cards, such as magnetic stripe cards. | [Table 2.
