Purpose

The purpose of this document is to define the conversion approach to create conversion for Object 1184 – Security Class for Treasury related transactions 
in S/4 HANA.

The security class is a grouping of similar securities. It defines the general characteristics of a group of similar securities. It is a standardised way of maintaining, managing and processing securities with shared properties. E.g. Bonds which may include corporate bonds, Government Bonds etc. Some of the common characteristics could be instrument type, currency, interest method, Nominal value type, interest calculation method, payment frequency, settlement type, interest method, product category etc.

The security class controls on how transactions for these types of instruments are valuated, settled, reported and accounted. The security class has close integration with market risk analyser, accounting, portfolio analyser and market data.

Key tables and fields: 

There are three tables involved in S4 with respect to the maintenance of the Security Class Data and these are:

• TWX2 – This table stores the security index class data. It has the security class, Index class and secondary index number information.
• VWPANLA – This table stores the asset master data related to securities. Some of the key information stored are Security class ID number, Product category, status, Product Type, Security type etc.
• VWPANLE – This table stores data related to interest bearing securities. It contains information on Security ID number, Product category, classification, Nominal value of the security, Issue start and end date etc.
• VZZKOKO – This table stores “Table condition header data”. It contains fields that hold specific information or linking keys about table condition header data such as company code, product category, key part and date condition effective from.
• VZZKOPO - This table stores “Table condition items”. The table is essential for managing and organising data related to table condition items.
• VWPBONO - This table stores data related to securities listing.

Table: TWX2 is the central table for defining security class in SAP S/4HANA Treasury and Risk Management (TRM). It holds information on security class, index class and secondary index number. The key fields of TWX2 table are:  

• RANL – The security class ID number is used for the unique identification of a security class. It can, for example, correspond to an official security ID number.  The Class ID number can be assigned by user which can be ISIN or other identifier. It acts as the link with table VWPANLA
• VVRANLWX – Secondary indexes can be maintained for securities in addition to the ID number. It helps to identify the security in external data source. Field RANL (ID Number) is used as a link between 2 tables VWPANLA and TWX2

Table: VWPANLA is the table in SAP S/4HANA TRM that stores the asset master data for securities. Some of the key information stored are Security class ID number, Product category, status, Product Type, Security type etc.

The key fields of VWPANLA are: 

• RANL – The security class ID number is used for the unique identification of a security class. It can, for example, correspond to an official security ID number.  The Class ID number can be assigned by user which can be ISIN or other identifier.

 The treasury function in legacy is carried out in the Quantum system and therefore for the conversion of this object, the data/details need to be sourced from Quantum and transformed as applicable for S4HANA in Syniti and load using LTMC for Security Class in S4HANA

Conversion Scope

The scope of this document covers the approach for converting active Treasury – Security Class Master from Legacy Source Systems (Quantum) into S/4HANA following the Master Data Design Standard - DD-FUN-050 Master Data Standard_1184 – Security Class Master Data

The data from legacy system includes:

1. Active records for Security Class which are still in use/valid and have validity date is > cutover date

The data from legacy system excludes:

1. All Security Class records which have a validity date in the past and are not in use in any exposure

List of source systems and approximate number of records <number of company codes to be confirmed>

Special Requirements

As the conversion involves a source system which is non-SAP, the below area needs special handling:

1. Extraction of Security Class record from source system i.e. Quantum is to be done manually.
2. Cleansing by business team to mark the Security Class records as blocked or completed, where applicable
3. The extracted records to be converted into a DCT and stored in the Syniti for transformation
4. Rating procedure if maintained in legacy should be within the correct validity period i.e. the validity should be “Equal to or Greater” than the cutover date.
5. The End of term date for the security class should be “Greater” than the cutover date.

Target Design

The Target design of the object 1184 - Security Class Master Data based on the MDS - DD-FUN-050 Master Data Standard_1184 - Security Class Master Data is as below

The technical design of the target for this conversion approach. 

Table – TWX2: Security Index Class - Mapping/Logical Fields

Note: Note: The fields marked as conditional are based on the field TWX2-RANL (Security Class ID).

Table - VWPANLA: Asset Master for Securities

Note: The fields marked as conditional are based on the field VWPANLA- VVRANLW (Security Class ID).

Table - VWPANLE: Interest Bearing Securities Data

Note: The fields marked as conditional are based on the field VWPANLE- RANL (Security Class ID).

Table - VZZKOKO: Condition Header Data

Note: The fields marked as conditional are based on the field VZZKOKO-SINCL (Security Class ID).

Table - VZZKOPO: Conditions Item Data

Note: The fields marked as conditional are based on the field VZZKOPO-RKEY1 (Key Part 1).

Table – VWPBONO: Security Index Class – Securities Listing Related Data

Note: Note: The fields marked as conditional are based on the field VWPBONO-RANL (Security Class ID).

Data Cleansing

For the purpose of the Object 1184- Security Class Master Data, the data cleansing should happen in the source systems i.e. Quantum as per below cleansing activity. The business cleansing is expected to be done by the business.

1. Identify all in active records for Security Class which are not valid and have validity date in the past
2. Identify all records which may still be having a validity date in the future but are against the counterparties which are nor relevant for migration

Exclude such records from the extraction from the Quantum and populate in the DCT

Conversion Process

The generic high-level process steps for the conversion are as below:

1. Extraction:
1. Extract from the source systems: Apply the selection parameters and data relevancy as mentioned in this specification, from the relevant tables
2. DCT: The DCT to be prepared if the data to be transformed and is part of the load file is not available in the Source system
2. Transform 
1. Transform fields by applying the fields and value mapping in the Syniti 
2. Generate and validate Pre-load files
3. Load
1. Load the validated Pre-load file using SAP's LTMC or the custom upload program as applicable. 

However, with respect to object 1184- Security Class Master Data - the conversion process will depend upon the DCT (Data Collection Template) which will be provided by the business based on the source data from Quantum system. This DCT will be used for transformation and generation of the pre-load file. 

The load will be done via LTMS using the "Security Class Product" template.

Data Privacy and Sensitivity

Extraction

Extract data from a source into Syniti. There are 2 possibilities:

1. The data exists. Syniti connects to the source and loads the data into Syniti. There are 3 methods:
1. Perform full data extraction from relevant tables in the source system(s).
2. Perform extraction through the application layer.
3. Only if Syniti; cannot connect to the source, data is loaded to the repository from the provided source system extract/report.
2. The data does not exist (or cannot be converted from its current state).  The data is manually collected by the business directly in Syniti. This is to be conducted using DCT (Data Collection Template) in Syniti.

The agreed Relevancy criteria is applied to the extracted records to identify the records that are applicable for the Target loads

Extraction Dependencies

Transformation

The Target fields are mapped to the applicable Legacy field that will be its source, this is a 3-way activity involving the Business, Functional team and Data team. This identifies the transformation activity required to allow Syniti to make the data Target ready:

1. Perform value mapping and data transformation rules.
1. Legacy values are mapped to the to-be values (this could include a default value)
2. Values are transformed according to the rules defined in Syniti
2. Prepare target-ready data in the structure and format that is required for loading via prescribed Load Tool. This step also produces the load data ready for business to perform Pre-load Data Validation
