Oracle CPQ can integrate with Oracle Enterprise Contracts, a comprehensive Contract Lifecycle Management solution. The guide provides detailed instructions for setting up the integration, including establishing a connection between the systems, creating commerce attributes, and configuring Contract Management integrations. The main purpose of this integration is to enable users to create and preview legal contracts generated in Enterprise Contracts directly within the Oracle CPQ application, ensuring seamless contract management throughout the transaction lifecycle. The document also includes appendices with sample XSL files that facilitate data exchange between the two systems during contract creation and preview.
