CNP received 814_08 A95 cancels on several 814_26 transactions during Hurricane Ike activities. ERCOT never received the 814_27s and after a month, ERCOT sent CNP an 814_08.
Next Step:
SIR was successfully implemented during the June 27th and 28th release.
ERCOT stated that this was a system issue as they do not normally send 814_08s on 814_26s. ERCOT is researching this issue to determine why 814_08s were sent in error to CNP. ERCOT will bring information back to Texas SET on what caused the 814_08s to go out in error.

Description:
This hard cancel, 814_08 A95, states in the graybox of the guide that "Review Period expired. MIMO Rules, ERCOT 23, TDSP 3, Not valid for CR cancellations", which indicates this is a MIMO Rule but the rule does not apply to 814_26 Ad-Hoc Historical Usage transactions. CNP was not expecting to receive an 814_08 A95 cancel on this transaction, therefore when we did receive the cancel we were required to force an 814_09out of our system to provide a response to cancel the request and close the Business Process Instance (BPI) for the initial request.
Since the MIMO rules do not apply to 814_26 transactions for this timeline requirement there should not be a need to continue this process for an 814_26 transaction.
Reason:
CRs would need to make additional requests for Ad-Hoc Historical Usage 814_26 for the same Customer/ESI ID since their original request has been cancelled. Requesting CR should be the only entity authorized to cancel the original 814_26 Ad-Hoc Historical Usage Request.
