Insights from SAP practice
Our consultants and developers write down what they learn in projects: from client copies, test data and data protection to HANA memory in S/4HANA.
SAP Basis: client and system copies
- SAP client copy: step-by-step guide, transactions and copy profilesA step-by-step guide to the client copy: local, remote or by export, every copy profile, test run, SCC3 and the follow-up tasks after each copy.
- New client copy tools from S/4HANA 1909: SCCLN, SCC9N and SCC1NWhat has changed in client copy since SAP_BASIS 7.54, which new transactions are available and what has stayed the same.
- Speed up an SAP client copy: performance, runtime and selective copiesWhat determines the runtime of a client copy, how to set parallel processes, copy method and target client correctly, and why data volume decides in the end.
- SCC3: reading client copy logs and fixing common errorsHow to read copy logs in SCC3, understand typical terminations and warnings, and resume a cancelled client copy cleanly.
- BDLS after a system or client copy: converting logical system namesWhy BDLS is needed after a copy, how to prepare the run, why it takes so long on large systems and how to avoid a subsequent run altogether.
- SAP system copy: step-by-step guide, homogeneous copy with SWPM and post-processingHomogeneous SAP system copy with HANA backup and restore and SWPM: a step-by-step guide, preparation, duration and a post-processing checklist.
- SAP system refresh: a QA refresh runbook from ramp-down to releaseRefreshing the QA system from production in phases: planning, ramp-down, copy, post-processing, ramp-up and release, with a checklist.
- SAP system refresh vs client refresh: when to use whichSystem refresh by system copy or client refresh by client copy: scope, downtime, transports, post-processing, space requirements and typical use cases.
- Creating, deleting and configuring an SAP client in SCC4Create a new client in SCC4, set role, change options and protection correctly, log on safely with SAP* and delete clients with SCC5 or SCC5N.
- SAP system landscape and client strategy: DEV, QA, production, sandboxHow an SAP system landscape is structured, which clients belong in which system and why every non-production system costs main memory in S/4HANA.
- Cleaning up technical tables: SAP housekeeping for production and copiesWhich technical tables grow unnoticed in SAP systems, how to clean them up regularly and why that makes every copy smaller.
- Reduce SAP non-production system size: five levers comparedHousekeeping, archiving, data aging and NSE, shell copy and time slices compared: what each lever does to shrink SAP test systems and SAP HANA memory.
S/4HANA: test data, data protection, memory
- Test data for S/4HANA: full copy, partial copy or generation?Five ways to get test data in S/4HANA compared: system copy, client copy, time-slice partial copy, manually created and synthetic data.
- Personal data in SAP test systems: what mattersWhy production data in test systems is a data protection issue, which approaches exist and what masking can and cannot do.
- SAP data scrambling and masking: anonymising test dataAnonymisation, pseudonymisation, masking and scrambling compared: six methods, typical pitfalls in SAP and a five-step approach to anonymising test data.
- SAP archiving in S/4HANA: reducing data volume for goodHow SAP data archiving works in S/4HANA, how it differs from ILM, data aging and NSE, where its limits lie and what it has to do with the size of your test systems.
- RAM prices have multiplied: what it means for S/4HANA landscapesAI data centres have been driving memory prices up sharply since autumn 2025. Why this hits S/4HANA especially hard and where to act: in production and above all in QA, test and sandbox.
