“The current logic at ERCOT is validating against the NM101 of MX regardless of the meter type. So, in the case below, even though the NM108 = 93 and the NM101= NONE we were expecting the REF~4P since the NM101 = MX. It is not clear if we should be going by, the NM101 = MX is required or the NM108 = 93 and the NM101= NONE.”
Reason:
This change control was written to correct/clarify the 814_20 REF~4P segment from ‘Required’ to ‘Optional’ when NM101=MX (Meter Exchange) and when NM101= MQ (Meter Information) because these processes are conditional based upon the meter/unmetered level data elements found in the NM1 loop. Hopefully this Change Control can be incorporated into ERCOT’s 2020 EDI translator changes and can be included in TX SET’s v4.0A implementation for ERCOT to systematically accept these 814_20 transaction types.
