Learn to adapt SAP ERP HCM programs so that they function without any problems after migration to the SAP HANA platform.
Learning Objectives

In this article, you will learn:

  • The basics of the SAP HANA platform
  • How to make sure your custom code is functionally correct
  • What to keep in mind when working with an in-memory database
  • How the traditional golden rules of database access have changed
Key Concept

SAP HANA is an extremely fast, in-memory, column-based relational database management system that allows applications to store and retrieve data as well as to perform complex analytical calculations.

Many companies are planning to switch to SAP HANA if they have not done so already. It is therefore essential that the SAP ERP HCM programs be fully functional and written in a way to make the best use of SAP HANA.

In this first article of my two-part series, I cover the considerations to keep in mind for custom coding when working on an SAP HANA implementation or migrating to an SAP HANA system—what areas you should look into and what coding to avoid for correct program function and good performance on SAP HANA.

I start with a brief SAP HANA overview. Then I show you how custom code must be changed so that the program function is not hampered. In addition, I explain the code constructs or parts of an SAP ERP HCM program that can be optimized to get the best performance on SAP HANA.

Examples of SAP ERP HCM coding with SAP ERP HCM tables clearly demonstrate both good code and constructs that should not be used.
