Purpose
This article intends to give a brief introduction of ALE distribution on the HR scenario concerning message type HRMD_*, followed by a disclaimer.
Overview
Application Link Enabling (ALE) is a technology that allows you to integrate data and business processes across systems. It allows, for example, an SAP HR system to synchronize organizational and employee data with other SAP components located in separated systems, such as CRM or SRM. Technically, this is done using Remote Function Calls (RFCs).
This communication is usually done in order to have changes to HR master data automatically distributed to other systems which also make use of it. These target systems can be SAP HR or non-HR systems which will use the data to create business partners. Examples of such systems are CRM, SRM, SEM, RPM, E-Recruiting, cProject, etc.
Disclaimer
The WIKI articles provided here intent to provide the reader some clarification on topics that normally cause confusion during the implementation of the distribution. There is no intention here to offer a step-by-step guide in setting it up from scratch. There are already plenty of good guides available, you can refer for example to the official documentation provided here (for EhP6).
In general, though, you might want to start by reading notes 200066 and 200343. You will find in its related notes section a reference to other relevant notes on this scenario.
