Purpose

The purpose of this document is to define the conversion approach to post AP open items without special GL indicator in S/4 HANA.

AP open items are related to vendor line items that have not been cleared and remains as open status during migration cut-off date.

• 3rd party vendors
• Intercompany vendors
• Employees
• Others

Amounts in legacy involve document currency, local currency and group currency. All currencies will be loaded accordingly unless there is a change in company design where local / group currency changes. Rates are as per the historical postings unless specific requirement calls for a fixed rate eg. group currency rate for consolidation purposes. Offsetting gl accounts in legacy documents will not be considered in this migration scope, they will be migrated in other objects scope eg. GL open item or GL balances.

Conversion Scope

The scope of this document covers the approach for converting active AP open items from Legacy Source Systems into S/4HANA following the AP open items Master Data Design Standard. 

The data from legacy system includes:

1. All open items with no special GL indicator, exclude parked item and noted item
2. Clearing date > migration cutoff date
3. Posting date <= migration cutoff date

The data from legacy system excludes:

1. Parked item
2. Noted item

Conversion Process

Data Privacy and Sensitivity

Extraction

Extract data from a source into . There are 2 possibilities:

1. The data exists. connects to the source and loads the data into . 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 ; 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 . 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

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:

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
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

Load

The load process includes:

1. Execute the automated data load into target system using load tool or product the load file if the load must be done manually
2. 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.
