Purpose
The purpose of this document is to define the conversion approach to create conversion for Object 1080 Mixing Ratios.
Mixing Ratios are the ratios which are maintained for mixed costing. The pre-requisites for maintaining mixing ratios are production version and production alternatives.
The document details out the field list, extraction criteria, scoping, mapping, transformation logic, generation of the pre-load file and loading of the same with respect to the object 1080 - Mixing Ratios.
Key tables and fields:
The table mentioned below is the main table used for Activity Rates in S4.
ctivity rates would be performed within the S4 system as a part of the month end activity.
The activity prices can be extracted from the legacy SAP system and loaded to S4 Hana. Migration object Cost rate i.e. “S4_CO_ACTIVITY_PRICE” can be used for migrating the planned activity prices. SAP has also provided function module “BAPI_COSTACTPLN_POSTACTOUTPUT” for migration of activity prices. Some activity prices will be extracted from ECC, while others will be provided by the business in the DCT page.
Conversion Scope
The scope of this document covers the approach for converting active from Legacy Source Systems into S/4HANA following the Master Data Design Standard.
The data from legacy system includes:
The data from legacy system excludes:

Conversion Process
The high-level process is represented by the diagram below:
Data Privacy and Sensitivity
Extraction
Extract data from a source into . There are 2 possibilities:
- The data exists. connects to the source and loads the data into . There are 3 methods:
- Perform full data extraction from relevant tables in the source system(s).
- Perform extraction through the application layer.
- Only if ; cannot connect to the source, data is loaded to the repository from the provided source system extract/report.
- The data does not exist (or cannot be converted from its current state). The data is manually collected by the business directly in . This is to be conducted using DCT (Data Collection Template) in
The agreed Relevancy criteria is applied to the extracted records to identify the records that are applicable for the Target loads

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

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

Load
The load process includes:
- Execute the automated data load into target system using load tool or product the load file if the load must be done manually
- Once the data is loaded to the target system, it will be extracted and prepared for Post Load Data Validation

Key Assumptions
- Master Data Standard is up to date as on the date of documenting this conversion approach and data load.
- is in scope based on data design and any exception requested by business.
