At the moment you hear a lot about the (necessary?) Change to the new ERP-Software of the SAP: SAP S/4HANA. What is it? Why should you change – must you change? What exactly is HANA, is the same as S/4HANA? And what is FIORI?
In short words:
HANA Is the new database of SAP
S/4 HANA are the applications already optimized for it and
FIORI is the new graphical user interface.
And yes, de facto you have to change (ca. Until 2025), because SAP has discontinued the previous solutions.
So the time is limited until you have to change the whole system over. On the way there you should not just throw all the old stuff into the boxes and unpack them again at the new place. You can compare it with moving into a new house – if you get rid of ballast and only take what you really need, the move will be a gain.
But the new house is not even there yet, it has to be designed and planned first. In this planning, you should not only consider that there are new technologies in the new house, but also needs of the residents – that is, the employees. These have been a big help when using the SAP system (i.D.R. SAP R/3) in the last 20 years you have probably already collected a few things that you would like to optimize.
That's why many IT consultants and IT training providers have a Roadmap, has outlined a way to approach the whole thing and implement it step by step. You will be assisted at each stage of the move by training the staff involved.
1. Step: S/4 HANA Delta Training
In the first step, it is important to enable the project team to help shape the new house. To do this, they must first be given the authority to help decide what the new S/4 HANA system should look like.
For this they need a basic knowledge, which in Delta training (what changes at all between SAP R/3 and SAP S/4 HANA?) is conveyed.
The entry is made via a 360° course, in which an overview of the whole area is given in 3 times 4 hours: so to speak the plot is marked out on which the new house is built.
2. Step: Process inventory / GAP analysis
The next step is to look together "What do we pack in the moving boxes?"
– Which existing processes should live on in the future in unchanged form?
– Which processes are obsolete and can be safely put on the road to bulky waste?
– Which processes need to be changed/optimized, based on what was shown in the Delta trainings about possibilities of SAP for process optimization? These could be individual facets, but also completely new processes.
SAP has several hundred Best practice processes published, which you could use as a template and incorporate into your own processes. Z.B. Here are template materials for all material levels (finished products, semi-finished products, raw materials).
3. Step: S/4 HANA On-Site Analysis
A key aspect is the employees who have been using SAP for 20 years and know,
– where a room is too small for you
– where you are missing a function or
– where they find error-proneness every day, which they would like to optimize or
– where you can use a new function, which does not exist today in this way.
On-site analyses involve going into the departments and talking to the employees: What is missing, where is the shoe pinching? This regularly results in very interesting collections of topics.
