2. 2 Pro-Active Transaction Resolution Measures 867s Received on Cancelled Service Orders

3. 3 Situation ERCOT periodically receives 867_03 Finals and 867_04s for service orders that are Cancelled in ERCOT systems. The Service Order Sub-Statuses that are considered Cancelled are: CR Requested, Customer Objection, ERCOT Operating Rule, Manual, Permit Not Received, with Exception, Unexecutable and Rejected by TDSP. This can indicate an out-of-sync condition between the TDSP and ERCOT. Mechanism for Handling 867 RCSO: Step 1: ERCOT produces 867RCSO data each Friday and submits a report file to each TDSP and CR via the ERCOT Portal Step 2: The TDSPs review the report line items and take one of the following actions: a) If the TDSP has cancelled the service order, no further action is required b) If the TDSP has completed the service order, they will initiate a day-to-day MarkeTrak issue and work with ERCOT to get ERCOT systems changed to complete. Completion of cancelled service orders will require the approval of the CR initiating the transaction. (Note: For Cancel by Customer Objection, the TDSP will honor the cancel in their systems) 867s received on Cancelled Service Orders
