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:

1. BOMS > 3 years
2. BOMS w/o Deletion flags
3. BOMS with active Materials in active Plants
4. BOMS that will be migrated to the To-Be Plant Mapping (Take in consideration the To-Be definition of Plants)

The data from legacy system excludes

1. BOMS inactive in the last 3 years
2. BOMS marked for deletion
3. BOMS with Inactive Materials in inactive Plants
4. BOMS belonging to Deleted plants (New plant Definition according with the To-Be Plant mapping)

Special Requirements

Specify any special requirements or considerations that may impact the data conversion process based on specific locations, regulatory compliance or system limitations. Clearly outline any regional or localization requirements such as country-specific data formats, legal reporting obligations or industry standards that must be adhered to (e.g., localization rules for countries like China).

If the data conversion involves third-party systems or external data sources, such as Icertis, describe any additional requirements related to data mapping, transformation logic, validation rules or security measures that must be followed.

Target Design

With Functional input, document the technical design of the target fields that are in the scope of this document.

The technical design of the target for this conversion approach.

Data Cleansing

All data cleansing should take place in the data source system as defined in this document, unless system limitations prevent it.

If data cleansing is managed outside of the source system (e.g. Syniti Migrate, 3rd Party Vendor, DCT), the necessary documentation must be produced and appended to this deliverable for sign-off.

Conversion Process

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

Data Privacy and Sensitivity

Summarize Data Privacy and Sensitivity Requirements, if any

Extraction

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

1. The data exists. Syniti Migrate connects to the source and loads the data into Syniti Migrate. 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 Migrate; 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 Migrate. This is to be conducted using DCT (Data Collection Template) in Syniti Migrate

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 Syniti Migrate 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 Migrate
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

• Data Object is in scope based on data design and any exception requested by business.

Any additional key assumptions.
