The Future of SAP BW

The Future of SAP BW

SAP Business Warehouse (BW) was first introduced in 1998. Since then, it has not undergone such a significant change as now - the transition to SAP HANA . Most companies already operate at BW on HANA or BW / 4HANA. What is the difference between them?

BW on HANA versus BW/4HANA
SAP BW powered by SAP HANA (or abbreviated as ‘BW on HANA’) uses old BW software already connected to the new HANA architecture (possible from BW version 7.4). The customer thus uses the old BW environment, but gains the benefits of a powerful column-oriented HANA database. That is significantly faster because it is located in the server's operating memory and not on disk. However, BW on HANA is not fully integrated with HANA at the application level and cannot use full potential of the new technology.

BW/4HANA 4HANA is a completely redesigned BW platform that operates above the HANA database. In addition to higher performance, the BW/4HANA also offers simplicity, flexibility in development and a number of functionalitiesthat are not available on the BW on HANA. Of course,it also includes a modern user interface.

MIGRATION
BW / 4HANA was introduced in 2016. Despite the many benefits, many companies are hesitant regarding the migration or they migrate only part of theirs systems. In order for the customer to get the most benefits from the new system, the migration to BW / 4HANA requires a complete remodeling of BW, which can be costly.

Support for SAP BW 7.5 (as well as support for the entire SAP Business Suite 7) ends in 2027. At the end of 2020, however, SAP postponed the support provision date due to slow customer migration (for the third time in total). Lately, support will be provided until 2030, but only for individual applicants. At the same time, however, it calls for them not to delay migration, as this is a time-consuming process.

THE END OF BW?
With the arrival of S/4HANA, opinions often emerge about the end of the BW module as such. The reason is that the number of operations that have been performed in BW so far can be processed and analyzed by S / 4HANA in real time directly in the transactions themselves due to its extreme performance. The presence of a BW module may therefore seem unnecessary at first sight. However, most companies still cannot do without BW. These are, for example, cases where a company draws data from several sources, whether internal or external. This data then needs to be cleansed, consolidated, harmonized and ensured that there is a 'single version of truth' – one correct data version.

The question isn’t therefore whether BW yes or no, but how to effectively use the functionality of the BW module together with the benefits that S/4HANA brings.

We have our own IoT solution to measure temperature.

We have our own IoT solution to measure temperature.

We have developed our own, affordable solution for automated human temperature measurement. Thanks to special sensors and an advanced measurement algorithm, which takes into account the distance of a person and the temperature in the room, it is possible to reconstruct the obtained data into the so-called heatmap and create an image well known from "thermal cameras".

The big advantage is that the device does not use a real camera that would capture the face. Thanks to that, it is secured personal data protection at high level. You will find this device at the entrance to the Fpt Slovakia building. The IoT solution was developed within two weeks by one of our colleagues, an IoT specialist – Tomáš Lörinc.

temperature Tomáš had the idea to create an automated temperature measuring device in his head right at the beginning of the pandemic. However, he decided to implement it only after the April company meeting, at the initiative of colleagues. This is not Tomáš's first IoT project, he has been working in this area for a long time. He worked on this particular one for about 2 weeks. A second prototype is currently being deployed, which was the logical outcome of the internal PoC project.

"Since my area of interest is mainly IoT, connectivity and HW, I would welcome advice from colleagues who are experts in another field. Rado Bálint helped me choose a suitable solution for data visualization."

Of course, there are also ready-made solutions in the form of thermal cameras. However, these are very expensive and their primary purpose is not to measure a person's temperature at the reception. Our solution is more than 10 times cheaper and at the same time tailor-made directly for our needs. The device is connected to the Internet and is able to communicate using the MQTT (SSL) protocol, making it one of the most versatile devices for automated temperature measurement. Last but not least, we care about the protection of personal data, which we thus control Of course, our device can be expanded at the customer's request with a camera with high resolution and face recognition, or a card reader and thus ensure that the temperature is assigned to a specific person,“ Tomáš adds.

We are constantly working to improve the device as well as its detection algorithm. Thanks to OTA updates, we are able to update FW devices even remotely. Tomáš sees other possibilities of use in the area of monitoring desk occupancy, which is currently a very popular segment. Thanks to a sufficient viewing angle, one sensor would be able to replace several motion sensors currently used for this purpose. Another possible area of use is the monitoring of premises with the remaining demand for personal data protection. For example, some airlines have a problem with the on-board toilet being used by more than one person at a time, the so-called Mile High Club. Such a sensor can unambiguously determine the number of people without invading privacy and notify on-board personnel.

Our company has been working on innovative projects for a long time and supports creative people, said Jozef Vojtko, Vice Director of Fpt Slovakia. And stated further that the crisis gave way to new technologies, innovative ideas, and at the same time accelerated their implementation in practice.

It doesn't always have to be big international things. Our colleagues proved it on several examples, either by automating internal processes or by automated temperature measurement. Tomas is an excellent example of this.
