CoreOne SAP Module
- Silvan Grüter
Introduction
In order to read and write the necessary data from and to SAP, the CoreOne SAP Module has to be installed on the SAP System. This document tries to give you a better understand what this SAP Module does and how it interacts with the CoreOne Suite.
CoreOne SAP Module
The CoreOne SAP Module is a collection of ABAP functions that gather data from various Info Types tables, filters the data in accordance to the provided filter and exposes the data. There are various functions.

RFC
With the installation, the documented functions will be exposed as Remote Function Calls - RFCs. This allows the CoreOne SAP Data Adapter to call those functions.
CoreOne SAP Data Adapter
The Data Adapter will then use the exposed RFC functions to read the data. It’s important to understand, that the Data Adapter gets the data in the same fashion, as they are stored within SAP. This is especially crucial for things like organizational assignments. Depended on how mutations are done within SAP, this can lead to different data provided to the SAP Data Adapter.
The Data Adapter then converts the data provided from SAP in accordance with the configured import configuration stored in the configuration of the CoreOne Universal Connector. The only transformation that is done on this level, is the merging of organizational unit assignments.
Merging of organizational unit assignments
If there are more than one record for the same employment (Note: this is determinated by the foreign_id configuration in the CoreOne Universal Connector), the records will be merged with the following rule set:
All connecting records will be merged into one record, resulting in one employment
The data is taken from the record, that is valid at the time of import
Any non connecting records are discarded
For example you have an employment that is valid from January till February, then a change in the Employment Type Sub Group from February to March, then no record till September, the September record will be discarded.
CoreOne Universal Connector
The CoreOne Universal Connector then maps the resulting data to the CoreOne Meta Directory in accordance to the configured import configuration.
