Purpose
The purpose of this document is to define the approach, scope, and rules for the conversion of Bank Master Data from legacy systems into SAP S/4HANA. The Bank Master includes information about House Banks and Bank Directory (External Banks) required for processing payment transactions such as vendor payments, customer refunds, and bank reconciliations.
This conversion ensures that all bank-related master data is available and consistent in the S/4HANA system to support business-critical financial operations post go-live. The data migration encompasses both:
· External Banks (from tables like BNKA): Used for storing details of banks globally (e.g., SWIFT, bank address, bank key).
· House Banks: Internal company banks used for executing payments and receiving cash (e.g., bank account number, account ID, GL account linkage).
The migration process includes the cleansing, transformation, mapping, and loading of this data in alignment with SAP's Business Partner and Financial Supply Chain Management framework, while adhering to data quality and audit requirements.
Conversion Scope
The scope of this conversion covers the migration of all relevant Bank Master Data from the legacy SAP ECC system to the SAP S/4HANA system. This includes both External Bank Directory data and House Bank configurations, ensuring continuity in banking operations such as payments, collections, and bank reconciliations.
The data from legacy system includes:
- Bank Key
- Bank Country
- Bank Name
- Bank Address
- SWIFT/BIC Code
- Bank Number / Routing Code
The data from legacy system excludes:
- Bank configuration for treasury or cash management tools not in active use
- Bank Communication Management (BCM) configurations unless separately scoped

Data Privacy and Sensitivity
Extraction
Extract data from a source into . There are 2 possibilities:
- The data exists. connects to the source and loads the data into . There are 3 methods:
- Perform full data extraction from relevant tables in the source system(s).
- Perform extraction through the application layer.
- Only if ; cannot connect to the source, data is loaded to the repository from the provided source system extract/report.
- The data does not exist (or cannot be converted from its current state). The data is manually collected by the business directly in . This is to be conducted using DCT (Data Collection Template) in
The agreed Relevancy criteria is applied to the extracted records to identify the records that are applicable for the Target loads

Data Collection Template (DCT)

| Field Name | Field Description | Rule |
| BNKA-BANKS | Bank Country/Region Key | The country in which the bank is located. ISO Country code e.g. AE for United Arab Emirates |
| BANKA-BANKK | Bank Keys | A Bank Key in SAP uniquely identifies a particular Bank in particular country. Bank Keys are created automatically in SAP using the following logic: If Bank Number is available, then Bank Number is equal to Bank Key. If Bank Number is unavailable, then SWIFT/BIC code is equal to Bank Key. Different length by country, for AE is 3 digits length e.g. for AE is 027 - SAP provides a guidance list |
| BNKA-BANKL | Bank Number | A Bank Number is a SAP terminology for identifying Bank Code, Sort Code, BSB Number etc. Different length by country, for AE is 3 digits length e.g. for AE is 027 - SAP provides a guidance list |

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 to make the data Target ready:
- Perform value mapping and data transformation rules.
- Legacy values are mapped to the to-be values (this could include a default value)
- Values are transformed according to the rules defined in
- 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
