ECMS Business Description Document (BDD)
In version 1.4 of the Business Description Document for the ECMS, we introduce the functions and properties of the ECMS to our counterparties and thereby support stake-holders in their go-live preparations. The document explains the different functionalities available to external agents (counterparties, CSDs and TPAs) and provides information on communication between the ECMS and those groups of users.

Message Usage Guide
The ECMS message usage guide describes how the ECMS communicates in A2A mode using ISO 20022 messages. It explains which schemata, attributes, business roles and annotations are relevant in this context. Furthermore, it informs how to get access to the ECMS group in MyStandards in order to view the content of necessary messages in more detail.

Catalogue of Messages & Credit Claim Files
The Catalogue of Messages provides a detailed description of the entire set of ISO 20022 messages used by the ECMS. It allows the reader finding the necessary information related to messaging which is needed to establish a functioning system of A2A-communication between ECMS and the ECMS Actors.
Note: The “Credit Claim Files” are only relevant for credit claims managed in the ECMS. For counterparties of the Bundesbank, this only applies to the cross-border use of credit claims via the CCBM. The domestic use of credit claims will be managed in MACCs.

Further information on MACCs can be found in the section:

U2A and A2A Roles & ECMS access rights matrix
The ECMS assigns predefined roles to users (counterparties, central securities depositories (CSD) and triparty agents (TPA). The business functions users are allowed to perform depend on the roles assigned to them and the respective data scope. A role consists of a number of rights that determine which functionality in the ECMS the user has access to. Each right relates to a business function for which the individual user either has read-only authorisation or which he can actively manage (execution). The system configuration in U2A mode provides a two-eyes principle and four-eyes principle for verification. In A2A mode this is done granularly according to business function in a two-eyes principle.

Explainer on authentication and authorisation of instructions in the ECMS
This document describes how ESMIG and the ECMS verify that an A2A message sender is entitled to perform the instruction described by the message and therefore prevent the processing of a message/file built and sent by an actor not allowed to perform the action.

Status codes in the ECMS
When the ECMS processes received instructions it assigns them different status codes depending on the process stage reached (e.g. matched). This document provides an overview of the various instructions (e.g. mobilisation of marketable assets) and the relevant status codes assigned by the ECMS. The ECMS sends corresponding A2A messages to inform about the status achieved in each case. U2A users can view the status of instructions via the ECMS GUI.

ECMS Connectivity Guide
The ECMS Connectivity Guide provides counterparties with a detailed description of technical connectivity to the ECMS for both the test and live environments. It explains the different communication modes available to counterparties and provides detailed information on the steps needed to subscribe to the Value Added Network Service Provider’s (VA-NSP) Services for the ECMS (U2A – user-to-application and/or A2A – application-to-application).

Documents on ESMIG connection

The central access point to the TARGET services, T2 (CLM and RTGS), T2S, TIPS and ECMS is the Eurosystem Single Market Infrastructure Gateway (ESMIG). For future communication with the TARGET services and therefore ECMS, every counterparty needs to be connected via ESMIG (directly or can use third-party technical access). The two network service providers (NSPs) SIA-COLT and SWIFT, licensed by the Eurosystem, are available for this purpose. Further documents on the connection via ESMIG as well as information on contracts with the network service providers SIA-COLT and SWIFT can be found in the "TARGET2/T2S Consolidation" section.
