Add new reject code "TCC" to notify REPs when the TDSP has rejected their request due to completing a competing order scheduled for the same date. Also add the new Complete Unexecutable Code "T024" to the REF~G7 segment of the 650_02 and 814_28. Add new code "TDR" for Two Business Days Notification Required in the REF~7G of the 814_13. Adding "SHF" as a valid reject code in the REF~G7 of the 814_11.
With the implementation of TX SET 4.0 where same day processing of MVOs, Switches, and extended hours for MVIs, Reconnects for Non-Payment there may be times where transactions may be competing for the same scheduled date. Also, with AMS functionality there may be more times where transactions are already completed just as another transaction is received by the TDSP requesting the same date. The TDSP would be unable to reverse any of these already completed transactions, therefore creating a need to provide the appropriate response to those transactions that cannot be processed for the same scheduled date. To create an easier notification process for these types of events it would be good for the sender, receiver and ERCOT to communicate a specific reject code to show that a transaction was rejected due to a competing transaction had already been completed for the same scheduled date. The reject code or complete unexecutable code would prevent delays in providing information back to the sender so that any alternative actions may be initiated such as changing scheduled date or determining if initial request is still valid.
Reason:
Prevents the need to read and interpret a text field if the reject was sent using an "A13 Other" rejection code each and every time, which could be very frequent.
