Purpose

The purpose of this document is to define the data conversion approach for creating Tax Condition Records in the SAP S/4HANA target system, as part of a Greenfield implementation.

In SAP ECC, sales tax condition records for pricing condition types that exist as part of the pricing procedure configuration and are stored in condition tables such as A*, KONV, and related master and transactional tables. These records are used to define tax elements such as sales tax, VAT, GST,  etc., across sales documents.
 
In SAP S/4HANA, the structure and usage of sales condition records remain largely consistent; however, data models may be simplified, and dependencies on country of sales,  receiver's country, business partners (replacing customer/vendor master records) become critical in ensuring consistency across sales functions.
 
This conversion aims to migrate active and relevant tax pricing condition records from existing ECC systems into S/4HANA by applying required transformation logic using Syniti as the data migration and transformation platform. The converted records will be loaded into the target S/4HANA system using standard SAP mechanisms such as IDOCs, BAPIs, or direct table loads where applicable.

Conversion Scope

The scope of this document includes the end-to-end approach for:

• Extracting existing Tax Condition Records from SAP ECC systems WP2 and PF2.
• Applying transformation and cleansing logic via Syniti to conform with the S/4HANA data model and business partner framework.
• Loading the transformed condition records into SAP S/4HANA while ensuring data integrity, correct assignment to condition types, condition tables, access sequences, and pricing procedures.

This process will support the migration of condition records such as:

• Output Tax (e.g., MWST)
• US Tax per document (e.g., UTXD)
• India GST ( e.g., JOCG )

The data from legacy system includes:

1. Tax condition records relevant for sales transactions, maintained across applicable tax codes and jurisdiction codes

2. Tax rates for output tax determination (e.g., VAT, GST, sales tax)

3. Tax exemption indicators or reduced rates as per customer-specific agreements

4. Effective and expiration dates for tax condition records

The data from legacy system excludes:

1. Pricing condition records (covered in CONV-1034 Pricing Condition Records Specification)

2. Rebate condition records (managed via Condition Contracts setup)

3. Withholding tax configurations (handled separately in the Master Data Migration scope)

Conversion Process

The high-level process is represented by the diagram below:

Data Privacy and Sensitivity

Extraction

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

1. The data exists. connects to the source and loads the data into . 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 ; 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 . 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

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:

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
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

Load

The load process includes:

1. Execute the automated data load into target system using load tool or product the load file if the load must be done manually
2. Once the data is loaded to the target system, it will be extracted and prepared for Post Load Data Validation
