Suite of HANA: ECC

Suite on HANA is an ERP Central Component that operates on the SAP HANA database. The ECC simplifies business tasks such as managing the logistics, finance, sales, and warehouse. ECC was developed with the intention that it could run on a wide range of databases such as MS SQL Server, Oracle, ASE, and others.

 

What is the Business Suite for SAP HANA?

SAP Business Suite for HANA. is a simple process which allows you to migrate to SAP HANA without moving your application to the latest version S/4. You can boost your business performance without the need to restructure the application layer.

 

SAP HANA

To explain in simplified language, SAP HANA is an in-memory relational database management system, which is developed and managed by SAP SE. The key functions of HANA include processing, retrieving, and storing the data for core business activities. It also supports Business Intelligence, Enterprise Resource Planning, and other applications.

The Advantage of In-Memory Database

Since it has an in-memory database, the CPU can get direct access to data rather than searching for it on hard drives. Another benefit of the in-memory database is that it transfers the data at a quick speed in comparison to storing the data on the disk. The disk allows you to only store limited data and the retrieving process is also slower.  

Other Features

  • SAP HANA can only provide the applications for carrying out different tasks such as HR, finance, sales, and logistics. The business enterprise has to take up the call on which is the best software to fit their needs.
  • Ever since the arrival of SAP HANA, the business enterprises have been able to improve their speed drastically when carrying out both Online Analytical Processing (OLAP) and Online Transaction Processing (OLTP).
  • SAP HANA offers a simplified architecture. Relational Database Management Systems has reduced its memory footprint. Online Analytical Processing and Online Transactional Processing are stored and processed in different databases. However, it can lead to bloating of the database footprint.
  • SAP HANA is a column-oriented RBMS that merges OLAP and OLTP as one structure. This allows organizations to curtain out memory usage and enhance performance.

SAP SE has been working on improving the SAP HANA services so that it can handle the database and software more efficiently. It will provide faster speed and flexibility. But older versions of the software will only receive support from SAP SE till 2025 after which the applications need to be updated.

If you have migrated to SAP HANA, you have to use the databases and tables as column structures. Apart from that, you also have to remove unnecessary aggregate tables and indices. In some cases, you are required to evaluate the customer design or rectified application.

 

SAP S/4 HANA

SAP S/4 HANA is the next advanced version of the Enterprise Resource Planning business suite. It is based on the SAP HANA in-memory database that helps large organizations to streamline their financial transactions and business data in real-time.

It needs to be seen that SAP S/4 HANA is relatively new and has made its appearance in 2015. But it has shown its potential by disrupting various industries including finance, banking, logistics, retail, and manufacturing.  

As an ERP Central Component user, you have got a couple of options. You can either migrate to the SAP Suite on HANA or move on to SAP S/4 HANA.

The features of SAP HANA have been discussed in the previous paragraph. So, it’s crucial to have a look at SAP S/4 features and benefits.

  • Centralizing data, financial compliance and monitoring is also much easier with SAP S/4 HANA. The companies do not have to wait for the financial close to view the Key Performance Indicators.
  • Automation of risk, compliance, and international trade management is better for SAP S/4 HANA in comparison to the Business Suite at HANA.
  • With SAP S/4 HANA, it is easier to detect fraud detection in real-time.
  • Even SAP S/4 HANA Supply Chain is superior and more effective than Business Suite  SAP HANA. It offers advanced inventory management, sales, and procurement of data. For example, you can monitor the condition of trucks through synchronized mobile devices. It helps in reducing costs and time.

 

SAP S/4 HANA Collaboration with SAP Fiori

SAP Fiori in combination with SAP S/4 HANA helps to personalize and streamline the User Experience of SAP applications.  It simplifies modern UX design principles to increase app visibility across all businesses and devices. User Experience can easily integrate with native solutions with SAP Fiori’s support. S/4 HANA provides more flexibility to the apps.

SAP Fiori can also get along well with the Business Suite on HANA. Fiori offers an optimal performance while running on SAP HANA and can be ported to other databases as well. The importance of SAP Fiori with HANA can be understood from the fact that if the Fiori transactional app is not present with HANA, it will slow down the mobile devices.  It fails to deliver a positive experience.

Sizing in Modern HANA Landscape

Sizing the hardware before migrating to SAP HANA is very important. If you fail to size properly, it may lead to the poor performance of the system with inappropriate response times. You can use the SAP Quick Sizer tool to note down the outcome and make calculations accordingly. This will provide the right hardware configuration.

Usually, the KPIs used in  SAP HANA version of the Quick Sizer comprises of three important elements-

  • Memory –  Memory is the most essential component while sizing environments determined by data footprint in SAP HANA
  • CPU footprint – If you want to improve your response time, it is important to provide sufficient CPU bedroom space, which is measured in terms of SAP Application Performance Standard.
  • Disk Size – SAP HANA also needs disk storage to store the database information. It also preserves the full image size of the business along with the current state of data and logging changes.
