Don’t Lift-and-Shift the Bloat: A Practical Guide to Data for Your SAP S/4HANA Conversion

If you move to SAP S/4HANA without tackling your data, you’re adding a lot of complexity and cost to your transformation.

I see this all the time: organisations spend millions on S/4HANA licences and infrastructure, but skip the unglamorous work of data volume management. The result? Oversized HANA boxes, more complex projects with longer test cycles and painful surprises in year-two cloud bills.

This newsletter is a practical walkthrough of how to think about data and sizing for your S/4HANA journey.

A Practical Guide to Data for Your SAP S/4HANA Conversion

1. Discover & Prepare

The SAP Activate methodology for a transition to S/4HANA, is a fantastic guide for a program. It mentions the analyses one should do in the Discover and Prepare phases.

Which includes – running a “Usage and Data Profiling” Analyses.

  • At this time it is also good to:
  • Assess your ECC system: data volumes, custom tables, technical logs, add-ons.

Identify data you don’t need in S/4HANA (old logs, obsolete transactional data, unused master data).

Top Tip:

Don’t forget to analyse current and historical organisational models – there may be organisational objects you don’t need in your target state – and therefore have a large opportunity to rationalise your data footprint, by only using the data related to your target organisational structure.

The biggest tip at this phase – is to treat data as a technical project work stream with its own plan, owners, and KPIs.
