The purpose of this document is to define the conversion approach to create Maintenance Strategy in S/4 HANA.
Legacy Plant Maintenance Maintenance Strategy is using a diverse range of formats across the different systems. There are instances where the same Maintenance Strategy is duplicated within and across sources, with informal words. This results in data inconsistency. As per SyWay design, Maintenance Strategy will be standardized.
The scope of this document covers the approach for converting active Maintenance Strategy from Legacy Source Systems into S/4HANA following the Maintenance Strategy Master Data Design Standard.
The data from legacy system includes:
All legacy strategies & packages assigned to valid legacy
The data from legacy system excludes:
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 | An initial extract will be provided to business to evaluate. Additional data/records may be required and these will be constructed via DCT. Enrichment of in-scope data may be required and will be added via transformation rules (business/technical). | 352 | S/4HANA | 352 |
Maintenance Strategy description will be made available in English.
Multi language is supported for Maintenance Strategy. Login via a different language will have its description displayed in the logon language if the language key is maintained in the Maintenance Strategy.

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.

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

For sites that are not on SAP-PF2 and WP2 systems, collection will be done manually in the data collection template.
The high-level process for DCT is represented by the diagram below:

Syniti will extract data from source system based on relevancy rule. This is done only ONCE at the start of the project.
The agreed Relevancy criteria is applied to the extracted records to identify the records that are applicable for the Target loads
| Req # | Requirement Description | Team Responsible |
