SAWA Interface Control Document v4.7 (marked up

1.1 Purpose This document describes in detail the data items required to be transferred between the external interfaces of the Gas Retail Market System (GRMS) and the market participants of South Australia and Western Australia to support the Gas Retail Market Procedures [RMP]. [...] For Western Australia, this document is the resultant output of discussions between AEMO and Market participants and minimal changes have been made to the definitive Business Specification [BS] and Interface Control Document [ICD] in respect of the operation of the GRMS in Western Australia. [...] Below the functional subgroup level the document aims to structure itself around the physical transactions and then to the logical process flows, as described in the BS, that use the physical transactions. [...] Market participants and their GBO Identifiers, the Business Roles assigned to a Participant and the Market Roles which a Participant is permitted to play in the market are to be communicated to the market prior to the commencement date of the market by the RMA as described in [RMP]. [...] The transaction group in the message header allows the routing function to send the message to the appropriate sub- system without having to interrogate the individual transactions.
