Purpose

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

Legacy Plant Maintenance Class is using a diverse range of formats across the different systems. There are instances where the same classes are duplicated within and across sources, with informal words. This results in data inconsistency. As per SyWay design, EAM classes will be standardized.

Conversion Scope

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

Grouping of objects with particular features can be achieved by creating Classes in the S/4 HANA system. A large number of objects can be managed and logically organized using this functionality.

Syensqo will utilize SAP Classification system (class and characteristic functionality) to assign any additional data attributes to following objects:

PM Assembly
Equipment
Functional Location
Document Management (DIR)
Task list
Measuring Points
Maintenance Plans

Classes allow you to group objects based on specific criteria that you define.

Classes are created for specific object types.
The Class Type determines which object types can be classified within a given class.
Characteristics are assigned to classes to describe the objects being classified.
When assigning a characteristic to a class, its values can be customized or overwritten as needed.

From the current source systems’ perspective, Class and Characteristic concepts already exist (but in slightly different structure). Class data 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.

The data from legacy system includes:

Classes with below Class Type
- 001-Material Class
- 002-Equipment Class
- 003-Functional Location
- 017-Document Management
- 018-Task List Class
- 037-Measuring Point Class
- 080-Maintenance Plans Class
Valid from [Current Date]
Status = 1 (Released)

The data from legacy system excludes:

Classes for Deletion (Deletion Indicator = X)

Class will be collected via DCT. An initial extract of the relevant classes will be provided in google sheet format to assist business in decision making on including any relevant classes from PF2 and WP2 as EAM Class.

Any additional classes that need to be created to support the new design may be added in the DCT.

A review and standardization will be done across all classes in the DCT.

Please see an indication of what will be baselined from source systems below and what will be constructed in the DCT.

Additional Information

Multi-language Requirement

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

Data Cleansing

No data cleansing is required for Classes 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).

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 classes that need to be created to support the to-be design

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 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

Key Assumptions

Master Data Standard is up to date as on the date of documenting this conversion approach and data load.
Data cleansing has met the required percentage threshold for the specified mock cycle and all preparation activities have been completed. (If applicable for Cleansing)
Data entries in DCT are target-ready data unless a specific transformation rule is stated for that field in the transformation rules.
Not all legacy Plant Maintenance (PM) Classes need to be mapped to S/4 HANA PM Classes. If any of the successor objects is dependent on a PM Class field with no mapped values, this will be an enrichment activity or manual transformation for the successor object to derive the PM CLass.

Any additional key assumptions.
