Purpose

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

Legacy Plant Maintenance Characteristics is using a diverse range of formats across the different systems. There are instances where the same characteristics are duplicated within and across sources, with informal words, and linked to Plant Maintenance Classes but are not used by Plant Maintenance objects at all. This results in data inconsistency. As per SyWay design, EAM Characteristics will be standardized.

Conversion Scope

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

Characteristics define a single custom field used to capture specific properties, attributes or values of an object. In SAP, Classes and Characteristics together form the “Classification System”.
For Syensqo, Characteristics will be used to record key attributes supporting reliability categorization and various analyses. It will be primarily used for information and reporting of attribute data across a large set of technical objects (e.g. Functional Location Structure). These Characteristics will be created centrally and assigned to relevant Classes.

From the current source systems’ perspective, Class and Characteristic concepts already exist (but in slightly different structure). Characteristic data and their allowed values are independently managed between PF2 and WP2. While these have been identified as source systems, a considerable amount of data construction will be required to support the production of data load sheets in the desired format.

While these systems serve as sources, extensive construction will be necessary to produce properly formatted data load sheets for S/4 HANA. 
The scope of this document covers the approach for converting active Characteristics from Legacy systems (PF2, WP2) and creation of New EAM Characteristics into S/4 HANA following the Characteristics Master Data Design Standard. 

The data from legacy system includes:

1. Characteristics assigned to Classes with below Class Type
   • 001-Materials: PM Assembly (PF2, WP2)
   • 002-Equipment class (PF2, WP2)
   • 003-Functional location (PF2, WP2)
   • 018-Task list class (WP2)
   • 019-Work center class (PF2, WP2)
   • 037-Measuring point (WP2)
2. Valid from [Current Date]
3. Status = 1 (Released)

The data from legacy system excludes:

1. Characteristics for Deletion (Deletion Indicator = X)

Additional Information

Multi-language Requirement

EAM Class description will be made available in English.
Multi language is supported for EAM Characteristics. Login via a different language will have its description displayed in the logon language if the language key is maintained in the Characteristics.

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

No data cleansing is required for Characteristics in the legacy systems. If any cleansing is deemed necessary, it will be performed outside of the systems.

As a result, the cleansed Characteristics data will be populated directly in the Data Collection Template (DCT).

Conversion Process

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

Collection will be done manually in the Data Collection Template for the following scenarios:

• For sites not on SAP-PF2 or WP2 systems
• For new Characteristics that need to be created to support the to-be design

Data Privacy and Sensitivity

Extraction

1. Syniti Migrate connects to the sources.
2. An initial extract of the relevant Characteristics will be loaded into a google sheet report to assist business with any standardization.

Data Collection Template (DCT)

Target Ready Data Collection Template will be created for EAM Characteristics  data with exception of some fields which require transformation as mentioned in the transformation rule.

1. The extracted report will be loaded into the required structure using the DCT.
2. Standardization activities (including deduplication, standardization and additions)  will be carried out within the DCT.

Delta Data Management: Initial collection will be done via the report and one-time load to the DCT will be performed. Any delta after the initial collection within the DCT will require business to take due diligence to ensure any subsequent delta cleansing is verified and aligned within the DCT.

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
