When creating a Software Model and publishing it into the Product Catalog, ServiceNow offers several Out of the Box (OOB) Workflows which can be linked to these catalogs, provided the OOB procurement plugin has been installed. An example of such a workflow is the Procurement Process Flow - Software.

The SAM Foundation and Procurement plugins are designed to complement each other. Whenever there is a need to procure software in instances where entitlements are not available, these OOB workflows become essential. With the Procurement Plugin installed, additional fields are integrated into both the Request and Request Item (RITM) tables.

For instance, on the Request tab, there is the inclusion of "Sourcable" field indicating whether the request can be sourced or not. Other crucial fields include "sourced" and "received," which play pivotal roles in driving the entire software procurement process in ServiceNow.

PS: SAM Foundation and Procurment Plugins are free of cost and comes with ITSM
