SAP S/4HANA

Do you want to make the transition to S/4HANA? We will plan your migration and bring you safely to S/4HANA with our tried and tested approach. Combine the best of both worlds: A new start without unnecessary old deadweight and, at the same time, take along proven solutions – including your historical data – where it makes sense and is useful.

Our S/4HANA Services:

  • Creation of your own for the S/4HANA migration – adapted to your goals and the operational and technical conditions
  • Consulting and coaching on migration issues
  • Implementation of the migration in a selective approach for minimum downtime, maximum flexibility, and security in the implementation
  • Architecture optimization in terms of cost and availability, including certified cloud solutions such as Microsoft Azure
  • Legally compliant decommissioning of your legacy systems and legacy data using cost-effective and proven storage technology
  • The takeover of the system operation

Analysis and Roadmap

Your goals when switching to S/4HANA can be diverse: perhaps you are only planning a technical upgrade to keep your system maintenance safe. Or you want to harmonize processes and, at the same time, implement organizational changes.

Whatever your reasons, we will design a robust roadmap for your S/4HANA migration, taking into account your goals as well as the operational and technical conditions.

The migration to SAP S/4HANA is a complex undertaking. We increase the security, add predictability, acceptance of the changeover by breaking down the entire project into logical building blocks, and individual projects that can be isolated. In this way, you remain capable of action throughout the whole project and can precisely control the change for your organization. Many preparatory and value-driving changes can already be made in ECC.

Datavard recommends

Your S/4HANA project should be broken down into isolatable individual projects. This means less risk and less complexity, and you have your hands free to manage organizational change.

Preparation

The migration time and effort, as well as complexity, will be significantly reduced by preparing your current system. There are several measures we recommend.

First and foremost, the archiving of data or systems that are no longer needed due to the HANA architecture (scale-up), effective data management is a must. Archiving offers enormous potential for reducing your storage and operating costs because, generally over 80% of SAP data is no longer actively used.

Using our certified technology (OutBoard™), you can outsource legacy and no longer required data and systems to cheaper storage solutions, while still keeping them accessible to users via the SAP front-end.

We’ll show you accurately which data can be archived using a patented procedure that measures the degree of utilization of your data – automatically and tool-supported.

We also check in-house developments for their use. In our experience, only a small part of Z programs are used long-term. And the less program code that needs to be adapted for S/4HANA, the more manageable the migration.

Additionally, you can make changes to the organizational structure already planned in the existing system or harmonize master and transaction data. This saves you time-consuming, risky mapping during migration and reduces complexity.

Selective Migration with Near Zero Downtime

Selective migration combines the advantages of classic migration approaches Greenfield or Brownfield into a hybrid model. You initiate a new start where it makes sense, eliminates outdated customs and practices and at the same time preserves what has been tried and tested.

Processes
  • Restart with a new configuration.
  • Old mistakes are history.
  • Process variants can be harmonized through extensive adaptations.
  • Tried and tested standards remain in place.
  • 1:1 Migration means that everything remains the same, for better or worse.
Data
  • Master and transactional data is created with new customizing or partially migrated from the legacy system.
  • The document flow for historical data is "destroyed."
  • Selective transfer (time slice and/or organizational units).
  • Option: Master and transaction data can be renamed and harmonized by our transformation suite.
  • The document flow for historical data remains intact.
  • New functions such as a business partner or new general ledger are also updated in the history.
  • 1:1 migration.
  • Option: Not needed data will be cleaned and/or archived beforehand.
  • Option: Master and transaction data can be renamed and harmonized by our transformation suite.
  • Document flow remains intact.
Code
  • In-house developments can be taken over but must be adapted or renewed manually to new processes and customizing, which is a time-consuming process.
  • Unnecessary developments or modifications remain in the legacy system.
  • Selective takeover of in-house developments.
  • Unnecessary developments or modifications are "removed" or deleted.
  • 1:1 migration.
  • Option: Unnecessary developments or modifications are "removed" or deleted beforehand.

Datavard is – as one out of four global companies – a member of  the SAP selective data transition engagement that defines innovative migration strategies for the transition to SAP S/4HANA.

Finish work with the legacy system on Fridays and start seamlessly with S/4HANA on Mondays – our Near Zero Downtime approach makes this possible without any problems.

It is based on a patented analytical method called Datavard Insights™. We measure the use of your data and can distinguish little-used data from frequently used data. Older and no longer actively used data such as customizing and master data, as well as historical data make up about 80% of the system volume and are migrated weeks before the go-live.

Current data such as current orders and purchase orders or changes to already migrated data are only transferred during the actual go-live. Through a precise measurement of your system and massive parallelization, even the most significant systems can be migrated comfortably within one weekend.

SAP S/4HANA in the Cloud

Many companies use the migration to S/4HANA as an opportunity to carry out a more extensive restructuring of their system landscape. In addition to migrating the system, we offer you the option of moving to the cloud at the same time.

Your advantages:

  • Maximum availability
  • Lower operating costs (especially for non-productive systems)
  • Flexibility in sizing (size and CPU)
  • Flexible structure of sandbox and project system
  • Integration of innovative platform services for analytics, collaboration, AI/ML, IoT, etc.

As independent experts, we are happy to advise you on the most suitable architecture and, if required, take over the technical operation with certified experts for Microsoft Azure, Google Cloud, and AWS.

Automated Data Validation

Testing is an essential step with every system change. However, in practice, it is often neglected due to the time and monotony involved. Also, real test coverage and complexity does not adequately reflect the reality and causes unpleasant surprises after the go-live.

With the aid of our intelligent technology, we automate the creation of test cases as well as the execution by more than 99%. Your migrated data is thus automatically checked for completeness and correctness.

Your advantages:

  • Developed together with the largest companies in the world
  • > 99% level of automation relieves the department
  • Detailed tests ensure complete transparency and comprehensive documentation for auditors and testers
  • Integration with existing test management tools such as Solution Manager or HP-ALM enables seamless integration into your test system

Decommissioning your Legacy Systems

Where to put legacy and no longer required ERP data? The legal requirements for storage and audibility (including GDPdU, ElDI-V, BAO) stipulate specifications are sometimes extended to up to 50 years as a result of international and industry-specific regulations such as HIPAA. The frequently recommended and continued operation of the legacy system in a virtualized environment is not an ideal solution for budgetary reasons and often does not comply with the applicable auditing standards (including Z1/Z3 access, IDW RS FAIT 3).

As part of our migration support, we take over the technical shutdown of your ERP system and the creation of a legacy system database. Our own software technology, certified by SAP and KPMG, makes it possible to store your data in a legally compliant and cost-effective storage solution. Users can access the data via your new S/4HANA system and the familiar SAP front-end.
