SAP S/4 HANA is an evolving solution which has
received much publicity. Customers are now starting to see what SAP S/4 HANA
means to them. Perhaps the most common pre-conception is that SAP S/4 HANA training is the next “upgrade” to
the old SAP Business Suite too which is coming into its tenth year. Due to the
history of the extremely successful SAP R/3, customers, in the main, are
content with the approach that every few years or so an upgrade will need to
take place to improve stability and enable future functionality.One
of the first questions asked by the experienced SAP customer is “how long will
it take to upgrade to SAP S/4 HANA?”, followed by a question relating to the
cost. Unfortunately that is the wrong question to ask. SAP S/4 HANA brings the
ability to re-shape and position for your IT systems within your business
processes and therefore it is time to add more value and use it to provide transformation.
SAP S/4 HANA provides a new way of working
There
are a number of articles around the new functionality that is held within SAP
S/4 HANA. With the SAP Fiori (Learn from SAP FIORI training) front end and the inclusion of embedded analytics, the days
of transaction codes are past. A business process from an IT point of view
could currently be something like the diagram below:
We
have seven steps, four separate IT tools to perform them and the time to
perform these tasks could be significant due to performance issues. In the
world of SAP S/4 HANA, all of this can be done from a single SAP Fiori tile. A
tile can represent many steps within a business process and the user can
navigate to other tiles, some of which may be analytical and others data entry.
All of the data is real time and the SAP Fiori screens provide a simple
intuitive user experience that reduces the time spent performing basic tasks.
How to get to SAP S/4 HANA from current
business suite solution
Assuming
you are looking to move a single Business Suite solution to a single SAP
S/4 HANA solution, there are two possible approaches that you can take:
·
System conversion
·
New implementation
The
system conversion aligns with the upgrade methodology that customers may be
more familiar with. However, a system conversion will always require some form
of functional changes as the current data needs to be converted to the new data
models. In order to fully utilize the new functionality and approach within SAP
S/4 HANA, the system usage, within business processes, will need to be modified.
Therefore, any move towards SAP S/4 HANA cannot be seen as an IT project as
previous SAP Business Suite upgrades have been. Instead, the move to SAP
S/4 HANA should be seen as a business-driven project to drive benefits both to
processes and users.
70%
of the SAP HANA (Learn HANA database from SAP HANA training) customers have followed the new implementation approach. The
common reason for this choice is that customers want to remove unwanted code
and bespoke processes and try to align to the new functionality within SAP
S/4 HANA. Starting with a clean and simple solution is a very attractive
proposition for many customers. In some cases, the additional cost of the new
implementation is not that significant when compared to a system conversion.
Get value from SAP S/4 HANA
This
is one of the most common questions. However, there is no one size fits all
answer. Each customer is unique and will have a number of interfaces in and out
of SAP and therefore need to internally review SAP S/4 HANA to see where
benefits can be realized.SAP provides free trials of SAP S/4 HANA which offer a
high level overview of the solution (See SAP training overview to know what SAP offers). However, most customers will
require more detail above and beyond the generic processes within the trial.
Therefore, some form of proof of concept or proof of value needs to be
undertaken. These exercises can be slightly more expensive than customers may
expect.
Performing
a traditional upgrade proof of concept for a SAP Business Suite solution can
take a few weeks, however an SAP S/4 HANA proof of concept will take slightly
longer. Once the system is up, various migration cycles will need to be
performed to enable the system so business users can start to analyze the
solution. Traditionally, the current test schedule would be run on the upgraded
box to see if any issues occurred as part of the upgrade.
