Purpose
The purpose of this document is to define the conversion approach to upload Materials - Purchasing View into S/4 HANA as part of the Material Data Migration.
Link to MDS: DD-FUN-050 Master Data Standard_2020-Material master-Purchasing data
Conversion Scope
The scope of this document covers the approach for converting active Materials - Purchasing View from Legacy Source Systems into S/4HANA following the Materials Master Data Design Standard.
This object is migrated after Material Basic Data, therefore only materials in scope for object "2019 - Materials Basic Data View" are in scope. Click here to go to the Conversion Spec for 2019 to see the full set of relevancy rules.
The Service Master will be loaded as Materials in the Target, therefore only services that meet the relevancy rules for object "2016 Service Master record (Lean Services)" are in scope. Click here to so to the Conversion Spec for 2016 to see the full set of relevancy rules.
| Source | Scope | Source Approx. No. of Records | Target System | Target Approx. No. of Records |
|---|---|---|---|---|
| PF2, WP2 | Materials: The Material Master Records will be extracted that meet the relevancy criteria of Material Basic Data. Services: There is no Purchase View data, therefore a DCT will be required for the records that meet the relevancy criteria. | Materials: Services: ** As per relevancy criteria | S4H | 207,315 |
Predecessor Object

Extraction
The source for Purchasing data for Materials is PF2 & WP2. This will be extracted by Syniti and the Relevancy criteria, as specified in object "2019 - Materials Basic Data View", applied to identify the records that are applicable for the Target load.
There is no source for Purchasing data for Services, therefore this data will be extracted by Syniti from a DCT. The DCT will only contain Services that meet the same Relevancy as Materials.

Extraction Dependencies
| Item # | Step Description | Team Responsible |
|---|---|---|
1 | Materials and Services in scope to be loaded as Material Master Basic Data must be identified before the extraction of Class data, so that we can limit the extraction to this sub-set of data. | Cutover |
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.
- Legacy values are mapped to the to-be values (this could include a default value)
- 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
