With SAP HANA, SAP provides a product that uses in-memory computing technology to optimize your business processes. SAP HANA comprises the required hardware as well as SAP HANA appliance software (SAP HANA database and data replication tools, for example).
In-memory computing can be used to significantly reduce the time required to access database content and to increase the processing speed of transactions considerably by storing the data in the main memory of the database system. As a result, large data volumes can be processed immediately and complex analyses can be performed extremely quickly and with up-to-the-minute data.
For SAP ERP, the integrated use of SAP HANA is supported in addition to the databases already supported and listed in the Product Availability Matrix (PAM). That means, in this case, that the scenarios that used to be performed on a relational database of your ERP system are now performed on an SAP HANA database. In this way, SAP enables you to use existing and optimized functions on an SAP HANA database. For an overview of the optimizations for SAP HANA, see SAP Note 1761546.
Note
You can, of course, continue to use SAP ERP on other databases. For details of the optimizations that are available in this case, see SAP Note 1835008.
Note the following when implementing SAP ERP with SAP HANA:
You can only use ABAP components on SAP HANA. If you have been using ABAP and Java components in a dual-stack system, you have to complete a dual-stack split and implement the ABAP and Java components on separate servers and databases. For more information, see the Dual-Stack Split Guide under
.For information about implementing SAP ERP with SAP HANA, see the Installation Guide under
.Note
Note that the use of SAP HANA in a side-by-side scenario is also supported. To do this, an SAP HANA database is put into use in addition to the existing integrated relational database, and the data is replicated between the relational database and the SAP HANA database. However, this implementation scenario is not suitable for running SAP ERP on SAP HANA.
