    Summary of Software Component Model Table

    The Software Component Model table ([cmdbsoftwarecomponentmodel]) in ServiceNow stores records of software components for various industries and use cases. It extends from the System Component Model table and automatically creates records based on normalized discovery models, either through automatic normalization or manual normalization.

    Key Features

    • A script generates software component models from normalized discovery models, using the system property com.snc.sam.softwarecomponent.choice.versionlevel to determine version granularity.
    • Version level options include: MAJOR, FULL, BOTH, and NONE, with the default set to BOTH. Ensure values are entered in lowercase.
    • Records are created based on the existence of FULL and MAJOR versions; two records are created for both, while only one is created for a MAJOR version.
    • Manual creation of records is possible, with references to the Software Product table available if using the Software Asset Management Foundation plugin or application.

    Key Outcomes

    Upon upgrading to the Zurich release, a scheduled job generates component model records for existing normalized discovery models. New normalized discovery models automatically trigger the creation of software component model records.

    Considerations include:

    • Changes to system properties apply only to new models, not existing ones.
    • Deleted or modified models won’t be recreated from original discovery models.
    • Manual re-normalization does not affect existing models unless they don't already exist.

    The Software Component Model [cmdb_software_component_model] table stores component model records that serves industries and use cases across different solutions on the ServiceNow Platform.

    Overview of Software Component Model table

    The Software Component Model table extends from the System Component Model [cmdb_sw_component_model] table that resides in the Data Foundation Model (sn_cmdb_foundation) application. The Software Component Model table can consist of various entities.

    A software component model record is automatically created whenever a discovery model meets either of the following conditions:
    • Is normalized with a normalized version set.
    • Is manually normalized with a normalized version set.
    A script runs to generate software component models from the normalized discovery models. This script uses the system property, com.snc.sam.software_component.choice.version_level, to determine the granularity of the normalized version. You can configure this system property to set the version level options, which include the following versions:
    • MAJOR
    • FULL
    • BOTH
    • NONE
    Note:
    The system property is configured to the BOTH version by default. You can modify this setting by selecting any of the other available options. When entering values, ensure they are in lowercase format. As an example, to set the system property to NONE, enter "none" in the value field.

    Two records are created in the Software Model Component table when a FULL version and a MAJOR version exist for the normalized discovery model. However, only one record is created if only the MAJOR version exists.

    You can also manually create a software component model record in the Software Component Model [cmdb_software_component_model] table. If you have the Software Asset Management Foundation plugin or the Software Asset Management Professional application while creating the record, you can reference the Software Product [samp_sw_product] table. If you are not using the Software Asset Management application, you need to type in the software product name.

    Upgrade information

    When you upgrade to Zurich release and later releases, the scheduled job, SAM - Generate software component model does a one time run to generate component model records for all existing normalized discovery models which are then stored in the Software Component Model table.

    After the upgrade, every time a new discovery model is normalized, the business rule, Create software component model that runs on the Software discovery model [cmdb_sam_sw_discovery_model] table gets triggered and automatically creates new software component model records for the new normalized discovery models.
    Note:
    The Software Discovery Model table is available if you have Software Asset Management Foundation plugin or the Software Asset Management Professional application running on your ServiceNow instance.

    Discovery model considerations

    The following are some considerations to keep in mind for discovery models:
    • System property changes: When a system property preference changes, the existing software component models retain their original settings. Only newly created version models adopt the updated system property.
    • Model deletion or modification: If you delete or modify a software component model, the system won't recreate it from the original discovery model.
    • Manual re-normalization: When a discovery model is manually normalized with new values, the existing software component model remains as is. The system creates a new software component model only if one does not already exist.
