BW/4HANA Simplifications (BW4SL)

- Last update 17Nov2020

One of strengths of BW for HANA aka BW/4HANA (BW/4, B4H, BW4) is simplification. This comes as something that can’t be seen (e.g. removal of approx. more than 5 million lines of ABAP SAP BW code) and also more visible changes that need to be adapted otherwise it will break BW systems once moved to BW/4 e.g.:

- changes to official interfaces (RSNDI, RSDRI)

- deletion of old/obsolete customer exits (CMOD) and BAdI methods for exit variables that are replaced by corresponding enhancement spots

- switch to new request management for all loading processes

- SAP HANA generated views are Calculation Views only (so called OneView model)

To get an overview of all “simplifications” that BW/4 comes with there see so called BW4SL notes available on SAP support site. At the time of writing this blog there were 66 SAP Notes like that. Each of the Note is dealing with particular BW functionality that was changed/simplified. Change is described also with possibilities how to dealt with it - like how to migrate/convert/adjust particular object. Below few examples of the Notes:

2444718 - BW4SL - MultiProviders

2443489 - BW4SL – InfoCubes

2479567 - BW4SL - Transformations

Central Note has number 2421930. All changes are also described in one central PDF document called Simplification List for SAP BW/4HANA:

Simplification List for SAP BW/4HANA 1.0

Simplification List for SAP BW/4HANA 2.0

SAP offers also interactive web page that provides a description of all changes having an impact when converting from SAP BW to SAP BW/4HANA called Simplification Item Catalog (SIC).

Well, do not get me wrong but this blog post is about solution from SAP which really doesn’t exists at time of writing. It is rather research project at HPI in Potsdam, Germany. What they actually do in the project is to exploring and testing possibilities of large scale ERP systems running on SAP HANA.

The sERP is continuation of new SAP mantra called “Simple”. This was announced on last year’s conference - SAPPHIRE NOW 2014. There will be a suite of products released called as S-Innovations or sERP where S means - simplicity. What is SAP trying to do with their products is to get them simplified. This is supposed to be simplification in terms of quicker implementation, simple testing, leaner maintenance, integration and upgrades together with having a user friendly GUI/UI. For sure that a lot of things will be changed and while going down the simplification road there will be things which will be lost. These kinds of drawbacks will be there in matter of losing vast value of flexibility which is provided by customization possibilities that is built in SAP. The sERP is considered to be similar as solutions like SAP Business All in One or SAP Business ByDesing. These are ERPs which are leveraging pre-configured best practices scenarios. Other point is that as long as it is cloud based solution there are further advantages such as infrastructure and maintenance.

First product from sERP suite is already live. It is SAP simple Finance or sFIN. It was Hasso Platner's keynote in the above mentioned SAPPHIRE NOW where he shared what led to development of the sFIN. He provided example of ECC’s FI module tables which can be simplified to just few of them: BKPF and BSEG as while FI and CO modules reply on the data form these two tables. The simplification was also driven by fact that running apps on HANA there is no more necessity to have aggregates, indices and even not using of table updates just inserts. Actually some of these types of things are now becoming redundant.

What else may come in future? Well there can be more ECC modules going through simplification. We can see maybe sLOG (Logistics, or sSD, sMM, sPP, sPM), sHR or sHCM, sMfg, sQM (Quality Management) etc. Even more also components of SAP ERP can come like: sCRM, sPLM, sSCM, sSRM.. Purely speculation but ERP and ECC can even morph one day into one system even together with BI (BW) system.
