ERCOT will stop creating the 814_27 response. The TDSP will create the 814_27 response and forward to ERCOT and ERCOT will forward to the CR.
Reason:
Current design causes the CR to receive an 814_27 response prior to the TDSP receiving the request. Thus, if the TDSP rejects the request the CR is never notified. This will change that flow and allow the CR to know if their request is accepted or rejected by the TDSP.
