Audit Guidance for DSV Flow Registration with SERI

This document is an audit guidance related to the registration of the DSV flow with SERI. It outlines the process for R2 Facilities to register their downstream vendor (DSV) chains under Appendix A 4(b). The registration allows R2 Facilities to cease tracking and verifying at the first R2v3 DSV. Auditors are required to request and review email confirmations from SERI to ensure the accuracy of the registered DSV flow. The document specifies that registration is a choice for each R2 Facility and that SERI does not approve the DSV flow merely because it is registered. Additionally, it mentions the necessity of re-registering changes with SERI prior to shipping to a new or changed DSV. The guidance emphasizes the importance of maintaining accurate audit trails for DSV flow accuracy and the corroboration of various core connections with the registered DSV flow.
