Purpose

The purpose of this document is to define the conversion approach to create Customer Material Information Records (CMIR) in S/4 HANA.

Conversion Scope

The scope of this document covers the approach for converting active Customer Material Information Records (CMIR) from Legacy Source Systems into S/4HANA following the Customer Material Information Records (CMIR) Master Data Design Standard. 

Pending Functional MDS before updating this Conversion Specs with following: 

1. Requirement for CMIR at Ship-to level instead of Sold-to. If using ship-to; may need to implement custom logic, potentially using a user exit like USEREXIT_CUST_MATERIAL_READ, to check for Ship-to specific records first.
2. Classification is new feature in S/4HANA. SME mentioned they want to use this. 
3. There are 18 Text configured for CMIR in QF2 and 17 Text Type in WQ2. All text type will be migrated?

4. Customer material and customer material description -> if blank copy Syensqo material and material description or excluded from migration.

The data from legacy system includes: 

1. All active Customer Material Information Records (CMIR); where customer and material still active.

2. Active customer is a customer without deletion blocks at general data OR customer without deletion flags in the same sales area (sales organization, distribution channel and division) as customer material info records OR customer without Sales and Distribution blocks.

3. Active material is a material where the combination of x-distr.chain status (MARA-MSTAV) and DChain-spec. status (MVKE-VMSTA) are the following:

   • blank - blank
   • blank - 63
   • 63 - blank
   • 63 - 63

4. Relevancy Criteria 4

The data from legacy system excludes:

Legal Requirement

As per US Department of Defence (DOD) a Cybersecurity Maturity Model Certification/ CMMC 2.0 is a mandatory certification for all contractors handling Controlled Unclassified Information (CUI) and Federal Contract Information (FCI). CUI includes sensitive technical data (e.g., design specs, system info) related to U.S. military and space applications. The Composites Business handles CUI and is therefore within CMMC scope. Without certification, the business risks disqualification from existing and future DoD programs.
It is mandatory to implement CMMC-compliant systems and processes to for all the organizations that are dealing with CUI.

Therefore, there will be one SAP instance specifically for CUI related entities. The migration for CUI related entities will be covered by US based data consultant using separate tools.

Special Requirements

Customer Material Info Records (CMIR)

A. Different SAP Instance Migration Approach

Due to compliance requirement, there will be one SAP instance for Rest of the World (ROW), one for China and one for CUI.

1. For entities in China, the data will be loaded into SAP China instance while the entire migration process will remain the same as rest of the world.
2. For entities which will reside in CUI, the migration will be handled by US based data consultant. 

Please refer to the link for the entity mapping for each instance. In case the data object is applicable for multiples instances, what business rule to follow?

 - To identify the record is for SAP ROW Instance, it will use below logic. 

1. The Customer Material Info Records (CMIR) has sales organization data in below entities. 

- To identify the record is for SAP China Instance, it will use below logic. 

1. The Customer Material Info Records (CMIR) has sales organization data in below entities. 

 - To identify the record is for SAP CUI Instance, it will use below logic. 

1. The Customer Material Info Records (CMIR) has sales organization data in below entities. 

Target Design

Customer Material Information Records (CMIR) Data strictly adheres to the Master Data Standard. The complete information of the tables and key fields that hold the Customer Material Information Records (CMIR) information follows the Master Data Standard document.

The technical design of the target for this conversion approach.

Data Cleansing

Conversion Process

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

The ETL (Extract, Transform, Load) process is a structured approach to data migration and management, ensuring high-quality data is seamlessly transferred across systems. Here’s a breakdown of its key components:

1. Extraction
The process begins with extracting metadata and raw data from source systems, such as Syensqo ECC system (i.e., WP2/PF2) periodically. The extracted data is then staged for transformation.

2. Transformation
Once extracted, the data undergoes cleansing, consolidation, and governance. This step ensures data integrity, consistency, and compliance with business rules. The transformation process includes:
- Data validation to remove inconsistencies.
- Standardization to align formats across datasets.
- Business rule application to refine data for operational use.

3. Loading
The transformed data is then loaded into the target S4 Hana system. 

For CUI instance, the ETL process will be similar, but it will not use Syniti tool.

Data Privacy and Sensitivity

Extraction

Extract data from a source into Syniti Migrate for S/4HANA ROW and S/4HANA China relevant entities. 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

For SAP CUI related entities, it will be alternative extraction process and the data will be stored in approved tools.

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

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

Load Phase and Dependencies

The Customer Material Information Records (CMIR) will be loaded in the pre-cutover period.

Before loading, it will have dependency on the configuration and data objects in the S/4 HANA. The configuration needs to be transported into the respective system first.

Business

Post-load validation is a critical step in data migration, ensuring that transferred data is accurate, complete, and functional within the target system.

1. Ensuring Data Integrity

After migration, data must be consistent with its original structure. Post-load validation checks for missing records, incorrect mappings, and formatting errors to prevent discrepancies.

2. Business Continuity

Faulty data can disrupt operations, leading to financial losses and inefficiencies. Validating post-load data ensures that applications function as expected, preventing downtime.

3. Error Detection and Resolution

By validating data post-migration, businesses can detect anomalies early, reducing the cost and effort required for corrections

Key Assumptions

• Customer Material Information Records (CMIR) Master Data Standard is up to date as on the date of documenting this conversion approach and data load. 
• Customer Material Information Records (CMIR) is in scope based on data design and any exception requested by business.
• There will be 3 SAP instances, one for ROW, one for China and one for CUI only.
• For SAP CUI instance, the migration activity will be handled by US based data consultant.
