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.
Integrated use of SAP HANA is also supported for SAP CRM, in addition to the databases supported according to the Product Availability Matrix (PAM). That means, in this case, that the scenarios that used to be performed in a relational database for your SAP CRM system are now performed exclusively in an SAP HANA database. SAP enables you to use existing and optimized functions on an SAP HANA database.
Note
You can of course continue to use SAP CRM in other databases.
Observe the following during the implementation of SAP CRM 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 the implementation of SAP CRM 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 CRM on SAP HANA.
