Purpose
The purpose of this document is to define the conversion approach to create 1038 Material BOM (Usage 1 & 4)
in S/4 HANA.
BOMS are actually used for all the Production process. All materials related with manufacturing activities have a Product Structure created by BOM/Master Recipe & Production Version. BOM takes a relevant part of the structure, where the components are defined to produce the Semi Finished and Finished products. The aim prior to migrate is to have a exhaustive data cleansing for BOM, as we know that some plants are having issues with them.
All valid BOMS will be migrated to the S4 Hana System, for all the relevant plants and for all the Semifinished and finished materials in scope (refer to CNV- 9070).
Conversion Scope
The scope of this document covers the approach for converting active 1038 Data register for BOMS from Legacy Source Systems into S/4HANA following the1038 Master Data Design Standard.
The data from legacy system includes:
- BOMS > 3 years
- BOMS w/o Deletion flags
The data from legacy system excludes:

Conversion Process
The high-level process is represented by the diagram below:
Data Privacy and Sensitivity
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)
Target Ready Data Collection Template will be created for data with exception of some fields which require transformation as mentioned in the transformation rule. DCT Rules

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

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