TARGET2 Integration until March 2023
- TARGET2 messages are generated via the workflow manager service SRVSWT/ SRVTAR.
- The SWIFT messages (MT 103 and MT 202) for TARGET2 differ from the 'Standard' SWIFT messages MT 103 and MT 202 with own specifications and rules.
- When generating the technical message format, some special features have to be considered for TARGET2 messages.
- Main official documention is in the “Target2 UDFS” “User Detailed Functional Specifications”.
Header Section 1 (Basic)
| Digit | Content |
|---|---|
| 1 - 3 | F01 (Standard) |
| 4 - 15 | BIC (Customized) |
| 16 - 26 | Customized Assignment |
In SRVSWT.MakeSwiftII() the actual message is generated in SWIFT format, e.g. the headers 1 - 5 are generated and passed as complete SWIFT message to SWIFT or they are written to disc as complete SWIFT file.
All parts of the output stream, which can be customized (at present OWNBIC and '0000000000'), can be set via customized functions (SRVSWT.GetOwnBic(in $T103 text) and “SRVSWT.GetCounter” (in $T103 text)).
In case of standard SWIFT messages, these functions return exactly what is currently implemented (OWNBIC and '0000000000').
In TARGET messages (identifiable by the content 'RTP' in $T103) the required items (e.g. a continuous counter per day) have to be implemented in these functions.
Header Section 2 (Application)
| Digit | Content |
|---|---|
| 1 | I or O (The function “GetDirection()” on level 5 returns the value for the first digit (I or O).) |
| 2 - 4 | 103 or 202 |
| 5 - 16 | Receiver BIC |
Normally, not the receiver BIC, but another BIC (e.g. the BIC of an internal payment system) is specified for RTGS / TARGET. Thus, it must be possible to assign this field as customized. This can be realized via the function “SRVSWT.GetIOBIC” (in $tag text, in $bic text)). It returns a BIC.
In case of standard SWIFT messages, this functions returns exactly what is currently implemented.
Header Section 3 (User)
| Tag | Content |
|---|---|
| 103 | TGT (Standard) |
| 113 | Customized Assignment, e.g. NNNN |
| 108 | Customized Assignment |
| 119 | Customized Assignment |
The function “TRNMOD.SwtCreateHeaderFunRTGSCusTag” (in tag text) provides the value for the passed tag that is set in this function for the customized assignment.
