Purpose

The purpose of this document is to define the conversion approach to create Bill of Material in S/4 HANA.

Conversion Scope

The scope of this document covers the approach for converting active Bill of Material from Legacy Source Systems into S/4HANA following the Bill of Material Master Data Design Standard.

A Bill of Materials (BOM) is a structured list of components, spare parts, or assemblies required for maintenance activities on technical objects like equipment or functional locations. It helps streamline maintenance planning, spare parts procurement, and work order execution.

The data from legacy system includes:

BOM Category:
1. E-Equipment BOM for relevant Equipment
2. M-Material BOM for relevant Assembly
3. T-Functional Location BOM for relevant Functional Location
BOM Usage = Plant Maintenance

The data from legacy system excludes:

BOM where the BOM Header is Assembly and all the BOM items are Assembly

For further explanation, a Material BOM for relevant Assembly excludes BOM Assembly Header that are not assigned to Functional Location, Equipment or Task List.

List of source systems and approximate number of records

Source	Scope	Source Approx No. of Records	Target System	Target Approx No. of Records
PF2, WP2	Bill of Materials will be extracted from PF2 and WP2	330,000	S/4 HANA	330,000
DCT	Bill of Materials for plants which do not have data existing from PF2 and PF2	nnn	S/4HANA	nnn

Additional Information

Multi-language Requirement

BOM header description will be retrieved from PM Assembly description. Alternate language availability will depend on PM Assembly alternate language.

Conversion Process

The high-level process is represented by the diagrams below.

The following represents the high-level process for Source System Extraction:

The following represents the high-level process for DCT:

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:
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.
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.

Extraction Dependencies

Item #	Step Description	Team Responsible
1	Only BOM linked to relevant Functional Location should be extracted.	Data Team
2	Only BOM linked to relevant Equipment should be extracted.	Data Team
3	Only BOM linked to relevant Assembly should be extracted.	Data Team

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.
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
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

Transformation Run Sheet

Item #	Step Description	Team Responsible
1	Ensure all mapping tables are up to date.	Syniti
2	In dspMigrate, select the wave –R3 S4/HANA – Plant Maintenance	Syniti
3	Go to Process Area Launch and Process the Object – BOM	Syniti
4	Review and Validate Error and Preload Reports	Syniti
5	Execute the transformation to prepare the target tables	Syniti
6	Validate data from pre-load and invalid reports by region	Business/Data owner
