AEMO API errors for multiple NMI requests

Question

When the Australian Energy Market Operator (AEMO) receives multiple API request for multiple National Meter Identifiers (NMI) including Get Service Points , Get Usage for Specific Service Points and Get DER for Specific Service Points, then how should the AEMO respond back for incorrect NMIs received?

Answer

The Accredited Data Recipients (ADR) are required by the CDS to include servicePointIds in the API request, which the Data Holders (retailers) convert to the corresponding NMIs prior to calling AEMO endpoints.
 If there are errors resulting from the NMIs provided to AEMO, then depending on the error, the retailer must either correct the issue and re-submit the request to AEMO or relay the error back to the ADR.

An example of this would be an unavailable NMI due to disconnection.

This is the expected behaviour and is factored into the CDS’s non-functional requirements.

If the issue were with the servicePointIds in the original request, then the Data Holder returns an appropriate error code to the ADR. The ADR then fixes the servicePointIds and re-submits.
