So, your organisation has decided on transitioning to SAP S/4HANA? Well, it’s an excellent choice on your part, indeed. But, have you ever wondered how you will pull off such a process without failing? It’s a huge-scale procedure, after all.
And, if you’re not careful in your approach, you might make a costly blunder.
But we don’t want such a hurdle in your path to greatness. Hence, in this blog, we’ll offer a guide on –
- What is Selective Data Transition?
- The approaches related to Selective Data Transition, and
- The benefits of the procedure.
So, without further ado, let’s get on with our topic immediately.
What is Selective Data Transition?
The term “selective” often refers to a restrictive migration procedure of the data available on your organisational infrastructure. Usually, if you choose a process related to those described above, it will only be possible to move a specific part of the data at once.
Nonetheless, that’s not how the Selective Data Transition method works.
It is a brilliant alternative to the New Implementation and System Conversion procedures that doesn’t come with their limitations. Therefore, with it, you can easily use your innovations in SAP S/4HANA while selectively re-using your investment.
An SDT method will also allow you to adapt to various customisations, processes, and data. In addition, you’ll get direct further-on processing of a partly-delivered sales order without any cutover effort while migrating it from ECC.
Sounds quite beneficial, right?
The Approaches Related To Selective Data Transition
A Selective Data Transition method is similar to DMLT (Data Management And Landscape Transformation) services to move data to the new SAP S/4HANA ecosystem.
And the whole transition process can be done through the following approaches –
1. Shell Conversion
In this case, your team will create a perfect copy of the already-existing PROD environment without any transactional or master data. However, you’ll have to include the configuration or ABAP Repository while you’re at it. Or else the approach wouldn’t work out at all.
2. System Merge
A system merge approach will have you merge your business data from three or more clients to curate an empty instance of the S/4HANA. These clients available here can either be from the same or different SAP ERP systems.
3. Client Transfer
In a client transfer process, you’ll have to select a client, the transactional data, as well as the underlying master with the required configuration. Once you’re done with it, you can start the transition procedure and move the target to the S/4HANA environment.
4. Company Code Transfer
A company code transfer is all about choosing a company code from your current structure to create a single client on the new S/4HANA system. You can either select the transitional data or the master information while going through the process.
Alternatively, you may also select the configuration without or with the master data to move from the previous ERP system to S/4HANA. The choice is yours.
Now, when it comes to creating a target system, you can choose between two options –
1. Shell Conversion
In the shell conversion approach, your team has to create a shell copy of the available PROD environment that comes with –
- The configuration, and
- The ABAP Repository.
… without any kind of master or transactional data. The project team will then use a system conversion procedure and convert the shell copy into a S/4HANA instance. There won’t be any transactional or master data available there, so the conversion process will complete quickly.
2. The Mix-And-Match Approach
In the mix-and-match approach, your project team will need to curate a new SAP S4/HANA installation at the beginning. And once they’re done with it, they’ll transfer the configuration and the ABAP repository accordingly. All of these will have to be done manually.
How Does The Procedure Benefit You?
If you’ve read until now, you can probably already guess how beneficial an SDT method will be for your organisation. But we’ll specify them a little here to improve your understanding of this aspect a little more. Hopefully, it can help you out.
Advantage – 1: No Business Disruption.
With this procedure, you can easily make a single unit go live without disruption. And if you want, you can also move a huge number of organisational units in multiple phases. It will suit your business needs and ensure the transition is happening quickly.
Advantage – 2: Say “No” To Obsolete Data.
A Selective Data Transition method can help you migrate only relevant historical data once at a time. This way, you can maintain a consistent document flow or process chain. For the same reason, leaving all of your obsolete data behind will be much easier too.
Advantage – 3: Do It As You Want.
As mentioned, an SDT method is quite flexible in almost every aspect. Therefore, it’ll be easier for you to work at your own speed and combine whatever project you want. If you wish, you can make a move in a single step or separate the whole transition into bits.
Advantage – 4: Unparalleled Customisation.
You can still implement or introduce new processes and harmonise or adapt to your historical data even when you’re making the transition. And, you won’t need to worry about the previous investments or good practices you’re working on.
Advantage – 5: No Downtime.
Apart from everything else, the downtime of a Selective Data Transition method is almost 0. On the other hand, the technical downtime of the same is only around a couple of hours. And you can also change your landscape with this process. So, that’s quite a win-win for you.
Is It The Right Option For You?
There’s a lot of information to process in this article, right? Yes, we know. And, that’s what’s making it difficult for you to come up with a decision, too, we understand.
However, there’s a trick.
Before you make a choice, we’ll ask you to assess your business first. For example, you’ll need to get detailed insights on the following –
- Custom code landscape.
- SAP and data landscape.
- Data quality status, etc.
cbs has an interactive, easy-to-use S/4HANA Transition Compass assessment tool. With this self-service assessment quiz, you can answer a couple of questions and determine which transition approach would be ideal for your organisation.
Leading experts have developed this self-assessment quiz for global process and data transformation, enabling end-to-end standardised business solutions and optimised S/4HANA implementations.
Once you have background information on all these aspects, you can then talk to your team and make your decision. Hopefully, that will help you out.
