Migration from SAP ECC to S4 HANA

How does SAP S/4HANA Make the Digital Core a Reality?
All improvements and capabilities in SAP S/4HANA can be explained by at least one component of this formula
Common themes
  • >>Unification of disparate data sources
  • >>Drill down to detail
  • >>Landscape consolidation

What Does it Mean to Simplify?

While it is easy to see an improved UX in action, sometimes it can be difficult to understand how we improve a data model. After all, SAP ERP for decades now has run some of the most complicated business processes in the world. Let’s take a look at an analogy to better understand what a simplified data model looks like.

Simpler Data Model : Inventory Management Example

On the left we see all the transaction and aggregate tables that were required to run basic inventory management. Most of these tables are aggregates and history to provide the subtotals needed for analysis tasks. Now on the right, you can see this is simplified to only 3 objects.  
How is this possible? The HANA in-memory database is so fast, we can compute the aggregates on-the-fly when it is required instead of computing them in advance, often guessing what users will need, and storing them.

Simpler Data Model Impact
  • >> No aggregates or redundant data
  • >> No locking
  • >> Full granularity for all processes
  • >> Operations in real time
  • >> Elimination of data reconciliation
  • >> More precision
  • >> Basis for simulations and predictions

Imagine what this simplicity can do for you

  • >> Allow your users to get whatever they need at any level of detail instantly
  • >> Eliminate the need to reconcile data sources or aggregates with the latest transactions
  • >> Reduce the complexity and storage requirements of the system
  • >> Improve the reliability and performance of the system by eliminating locking (HANA is an insert-only DB)

A Digital Interface for a Digital World

Soft Financial Close Anytime

Now that we have examined a simpler data model and improved UX, let’s take a look at just one example of new capability: soft financial close.

Post Goods Issue (PGI)

Second, a supply chain example. Whenever goods need to move from one place to another, a follow up financial task called a Post Goods Issue (PGI) must occur. Since inventory information on traditional systems is scattered around multiple tables, a PGI requires locking the tables so the transactions can post. In a high volume environment, this locking means that everyone else must wait in order to proceed. What if we could simplify the underlying data model so that this locking was no longer needed? We can do this with the HANA in-memory database (more on that later).

Reduced IT Complexity
Impact on IT Landscapes
  • >> Reduced storage
  • >> Less replication
  • >> Less network load
  • >> Faster restart after failover
Example with Finance Data

While it is nice that the business can achieve some awesome benefits from a simpler data model, what is in it for IT? Combined with historical archiving, the database can become much smaller without all that redundant aggregate data. This results in storage savings, faster backup and recovery, and improved reliability (due to less locking). IT stands to benefit just as much as their counterparts in the business. The example on this slide is from an early adopter of Simple Finance, the predecessor of S/4HANA Finance. For more information on HANA database sizing, visit this page: service.sap.com/sizing
