SAP HANA Use Cases

Here are typical use cases for SAP HANA.

SAP S/4HANA

The core use case is the combination of Analytics and Transactions in the environment of one SAP S/4HANA system. This results in data that is operational and available in real-time.

Transactional Systems

  • Many Users
  • Low data amount
  • High Reliability

Transactional Applications include:

  • Product planning
  • Inventory management
  • Shipping and payment
  • Sales force automation
  • Supply chain management
  • Customer relationship management

The transitions to SAP S/4HANA typically fall into one of 3 transition scenarios:

  • New Implementation – new or existing SAP customer implementing a new SAP HANA S/4HANA with initial data load.
  • System Conversion – complete conversion of an existing SAP Business Suite to SAP S/4HANA.
  • Landscape Transformation – consolidation of current regional SAP Business Suite applications or selective data transformation into one global SAP S/4HANA system.

SAP BW/4HANA

The core use case is managing consolidated data across the entire enterprise using a standardized data model to support real time decision making.

Analytical Systems

  • Fewer users
  • Huge data amount
  • High performance

SAP Business Warehouse and analytics applications typically include:

  • Business planning & analytical services
  • Enterprise reporting, query, and analysis
  • Enterprise data warehousing
  • Data from SAP & non-SAP applications
  • Native SAP HANA as a technology platform

Moving to SAP HANA

All SAP Business Suite customers will need to migrate their applications to S/4HANA (optimized for the HANA database) in addition to the database. 2027 marks SAP’s EOS (End of Service) for all databases other than SAP HANA.

Moving to SAP HANA

So what happens if you don’t move to SAP HANA?

  • Regulatory Compliance

    Outdated software won’t be updated to adhere to new data management regulations, creating compliance risk - especially critical for highly regulated industries: healthcare, finance, etc.

  • Decreased Reliability

    As the software becomes ever-more obsolete; unfixable code bugs and incompatibility with related applications lead to more crashes and lost productivity.

  • No New Application Functionality

    Staying down level on SAP applications means companies will be missing out on new application functionality, stalling their business transformation and limiting innovation.

  • Higher Cost

    Higher costs associated with lost productivity coupled with expensive maintenance packages from either the source application owners or 3rd party service providers.
