1.     Introduction

The T2 User Testing (UT) started on 01/12/2021 and prior to this test stage the software was tested by
Central Banks in Central Bank Testing (CBT) and in the Eurosystem Acceptance Testing (EAT). Some
software limitations were identified in the course of these test stages and these limitations will be
gradually lifted during UT.
The objective of this document is to provide an overview of these limitations in such a way that parties
involved in UT are informed, adapt their detailed testing plan accordingly and do not raise incidents on the
documented limitations.

This overview will present the limitations in three categories:

     1. Functionalities not yet released or delivered,
     2. Functionalities delivered but still impacted by open defects, and
     3. Functionalities delivered that the Eurosystem has not fully tested yet

The timeline and availability of other TARGET services (i.e. TIPS and T2S) for end-to-end testing with T2
is provided in User Testing Terms of Reference (UT ToR) published on the ECB website. Any temporary
changes to the principles mentioned in the UT ToR will be listed in section 2.1 of this document. Also, in
situation when any of the testing principle mentioned in UT ToR needs to be clarified/detailed with
additional information, then these details will be included in section 2.2 of this document

In addition to this fortnightly testing conditions document, starting from 14/02/2022, the particular testing
conditions applicable in User Testing for the beginning of each testing day is being communicated on a
daily basis by the National Service Desk.

Based on the request from the participants, the information on Minimum Reserve interests applied in User
Testing Environment, is now included in Annex 2 of this document.

2.     User Testing Conditions

The date of the status presented below is 17/06/2022.

     2.1   Temporary adaptations to the UT ToR principles

As mentioned in the UT ToR (section 4.6), the Central Banks and the T2 participants shall follow the
recommendation document (CLM/RTGS Reference Data / recommendations for setting up data in
CRDM) for reference data, in order to ensure the successful propagation of data from and/loading in
CRDM to CLM and RTGS systems.
With the deployment of the CR74 and CR75 on 01/04/2022, these recommendations are enforced by the
system.

Also, the timeline mentioned (in section 4.3 of UT ToR) for the Migration Weekend Dress Rehearsal
(MWDR) for User Testing phase with T2S and TIPS services has been replanned and the current time
period to conduct the MWDR is on 16 and 17 July 2022.

In addition to support the testing, it was agreed to extend the testing time in UT environment, with a delay
to the start of EoD processes from 15:30 to 16:30 CET. This change was implemented as of 14/03/2022
and shall last until end of June (i.e. 30/06/2022) with further possible extension. In general, the extended
testing time will apply to days with standard day schedule (i.e. Monday-Thursday), while the timing of the
release day schedule on Fridays will remain unchanged. The table below shows the T2-T2S - CLM/RTGS
- testing schedules during the extended period of testing time.

As of 23/05/2022, in order to tackle the RTGS/GUI issues and A2A communication issues which was
caused by the long running queries triggered from “Query message screen”, the pertinent GUI screen were
adapted with a rebuild of the search criteria so that only either Inbound or Outbound option can be selected.
In addition, the participants are recommended to use the additional search criteria (e.g. Message Type,
BICs) to avoid the queries impact on the system resource. These temporary measures will be applied until
the SQL queries are optimized for the GUI (i.e. A2A queries are not impacted) but will be removed with Go-
Live at the latest. A more precise date cannot be provided at the moment.

       2.2     Complementary information to UT ToR

TIPS and T2S Liquidity Simulator (UT ToR - section 9.2)

The TIPS and T2S liquidity simulator software is partially (with issues blocking testing of CLM U2A Liquidity
monitoring and CLM pull U2A Inter-service liquidity transfers) available for testing from 01/04/2022.

The testing can be conducted after the account and liquidity details for those accounts are loaded into the
system. So, in order to perform this load, the T2Ps submitted the TIPS and T2S simulator - cash account
liquidity reference data template 1. After the data checks, the liquidity was loaded into the system and made
available for testing the TIPS and T2S Liquidity simulator from 11/04/2022.

Similar to the first load, after the data checks, the liquidity was loaded into the system and made available
for testing the TIPS and T2S Liquidity simulator as part of the second load from 30/05/2022.The timeline
for the next load will be planned based on the requirement from the participants.
