Purpose

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

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

Conversion Scope

The scope of this document covers the approach for converting active Classes from Legacy systems (PF2, WP2) and creation of New Work Centers into S/4 HANA following the SyWay Work Center Master Data Design Standard.

A Work Center is an organizational unit that defines by whom or what a maintenance or production task is performed. The Work Centre has a capacity to do work and the activities performed by them can be costed by setting rates for those activities. A Work Centre can represent either people or machines or both. 

Main Work Center
Main Work Centers define the execution and organizational ownership of work management objects such as Notifications, Work Orders and Maintenance Plans within a Maintenance Plant.

They represent the work group team leaders or supervisors who organize and manage the maintenance workforce on a day-to-day basis. This includes coordinating both planned maintenance and unplanned breakdown work and effectively merging the two based on daily priorities and resource availability.

Work Center Category Consideration
Work Centers are distinguished by their Work Center category (e.g. Production Work Center or Maintenance Work Center). The category selected determines which data fields can be maintained in the Work Center master record.

For Plant Maintenance purposes, the default Work Center category will be Maintenance Work Center. However, if the Work Center is intended to represent a machine, the category should be set to "Machine".

Within the Work Center master data, the Work Center category is used to identify it as a Plant Maintenance Work Center. Additionally, a Control Key is maintained to specify the business transactions (i.e. such as scheduling or costing) that are applicable to the Work Center when used in maintenance task lists or maintenance orders.

The data from legacy system includes:

1. Object Type = A (Work Centre)

The data from legacy system excludes:

1. Work Center for Deletion (Deletion Indicator = X)

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	Class will be collected via DCT. An initial extract of the relevant work centers will be provided in google sheet format to assist business in decision making on including any relevant classes from PF2 and WP2 as EAM Work Centers. 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.	4,500

Additional Information

Multi-language Requirement

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

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 Work Center in the legacy systems. If any cleansing is deemed necessary, it will be performed outside of the system.

As a result, the cleansed Work Center 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 classes 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.

1	Extract data from source system based on relevancy rule	SyWay Data Team
2	Google Sheet report pre-populated with PF2 and WP2 information to be generated based on relevancy criteria.	SyWay Data Team

Selection Screen

If applicable, this section will give the details on any selection screen parameters, including the parameter type, that are required to be entered to ensure consistent data extracts.

Data Collection Template (DCT)

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

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

Key Assumptions

• Master Data Standard is up to date as on the date of documenting this conversion approach and data load.
• Data entries in DCT are target-ready data unless a specific transformation rule is stated for that field in the transformation rules.

Any additional key assumptions.
