Purpose

The purpose of this document is to define the conversion approach to create PM Assembly / Construction Type in S/4 HANA. For the purpose of this document, the term Construction Type shall refer to the object PM Assembly / Construction Type.

In SAP Plant Maintenance (SAP S/4 HANA EAM), the Construction Type is a material master reference assigned to a technical object (equipment or functional location) to represent its standard design or assembly structure. This allows the system to link standard data such as Bills of Materials (BOM), Task Lists, and Catalogs to multiple technical objects that share the same physical construction 

The Catalog profile assigned to the construction type is used to define the Object Parts, Causes, Damages of the asset.

Below are the guiding principles of the Construction Type:

  • Grouping Similar Assets:
    A Construction Type (CT) is created to group assets that share similar construction characteristics and are built using the same components.
  • Standardized Maintenance Strategy:
    Each CT is linked to a specific maintenance strategy. If the maintenance strategy differs, a separate CT is required.
  • BOM-Based Structuring:
    CTs are defined based on Bill of Materials (BOMs) that apply across similar asset types. These BOMs outline the construction hierarchy using sub-assemblies.
  • FMECA-Driven Classification:
    CTs also take into account Failure Modes, Effects, and Criticality Analysis (FMECA) codes relevant to the construction of the asset, supporting reliability-centered maintenance planning for all similar types of Assets.

Construction Type needs to be constructed as a logical grouping based on the above.

Conversion Scope

The scope of this document covers the approach for creation of Construction Type in S/4 HANA following the PM Assembly / Construction Type Master Data Design Standard. 

The creation of Construction Type follows the endorsed EAM Core Data Design describing the Asset Identification Methodology.

Legacy system did not have the concept of using PM Assembly in the similar manner as S/4 Hana. Hence there is no extraction of Construction Type required from Legacy.

The data from legacy system includes:

  1. All active Material Master with the Material Type from the below list:
    1. IBAU-Maintenance Assembly
    2. Z750-0 Aggregates PM IBAU (PF1 only)
    3. ZZ90-Maintenance Assembly (PF1 only)
    4. ZIBA-Maintenance Assembly (WP1 Only)

The data from legacy system excludes:

  1. Construction Types marked for deletion (Deletion Indicator = X)

Construction Type will be collected via DCT. An initial extract of the relevant Construction Type will be provided in google sheet format to assist business in decision making on including any relevant Construction Type from PF2 and WP2 as Construction Type in S/4 HANA.

Any additional Construction Type 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 Construction Type 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

Construction Type description will be made available in English.

Multi language is supported for Construction Type. Login via a different language will have its description displayed in the logon language if the language key is maintained in the Construction Type.

Data Cleansing

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

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

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 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 cleansing has met the required percentage threshold for the specified mock cycle and all preparation activities have been completed.
  • 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 Construction Type need to be mapped to S/4 HANA Construction Type. If any of the successor objects is dependent on a Construction Type field with no mapped values, this will be an enrichment activity or manual transformation for the successor object to derive the Construction Type.

Any additional key assumptions.
