Best SAP test data tools in 2026: S/4HANA and ECC compared

Inside SAP or outside it?

Add-ons are installed in each SAP system, usually by transport, and are upgraded with it. Tools outside SAP connect through OData or the database and install nothing in SAP, which matters for clean core and RISE with SAP landscapes. See SAP clean core test data.

S/4HANA, ECC or both?

SAP TDMS cannot be used on S/4HANA, and Velvet Mind's tool starts at S/4HANA 2023. ECC mainstream maintenance ends at the end of 2027, so most teams need a tool that covers both during migration. See SAP TDMS alternatives.

How is data reduced?

By date, by company code or by business process. A reduction that keeps an order with its deliveries, billing documents and postings lets Order-to-Cash tests run end to end. See time slicing.

Do non-SAP systems need the same values?

Most SAP processes touch a CRM, a bank or a data warehouse. If the masked customer in SAP must match the one in Salesforce, check that the tool covers those systems with the same rules.

Synthesized

Runs outside SAP, on-premises or as SaaS, and reads S/4HANA and ECC through OData or a read-only HANA user, so nothing is installed in SAP. It reduces data by business keys or dates with time slicing that keeps processes complete, generates customers, orders and employees that pass SAP's validations, and applies the same masked values in Salesforce, Temenos, Avaloq and other systems. Test data goes into Tricentis Tosca, UiPath and CI/CD pipelines. Sold on SAP Store.

Watch for: BW, CRM, EWM and GTS are not listed, and pricing is through sales. Start with a free 30-minute health check or a 10-day validation.

Qlik Gold Client

Qlik's SAP test data tool, formerly Attunity Gold Client. A certified ABAP add-on, installed by importing transports, that copies referentially complete subsets of SAP data into development, test and QA clients and masks personal data during or after the copy. It covers a wide range of SAP components, including CRM, EWM, GTS and BW. See Qlik Gold Client alternative.

Watch for: it needs a shared file system of at least 100 GB visible to source and target, and its pages do not describe non-SAP systems or generated data.

SAP add-on suites from SAP specialists

Suites from SAP-specialist vendors that run on the ABAP stack. They create shell systems, copy lean clients by time slice or company code, copy single business objects on demand, and scramble sensitive fields during the copy. Some carry SAP certification for S/4HANA. Some add SuccessFactors copying and masking through separate add-ons.

Watch for: they work inside SAP landscapes; non-SAP systems and generated data are not stated.

SNP Test Data Organizer

Part of SNP's Kyano platform. Built into the SAP architecture and run from SAP GUI or Fiori, it selects data by time slice, organisational unit or business object and scrambles it during extraction, with preset contexts for common processes.

Watch for: non-SAP coverage is not stated.

Velvet Mind Data Refresh Operator

An ABAP application with a central control system that copies time slices and follows dependent objects until nothing required is missing, with masking built in.

Watch for: it supports S/4HANA 2023 and later only, and deliberately not ECC.

SAP TDMS

SAP's own reduction tool for ECC: time-based reduction, shell creation and scrambling, through DMIS add-ons on the sender, receiver and central systems.

Watch for: SAP has not released it for S/4HANA. For S/4HANA Cloud Public Edition, SAP offers a separate Test Data Refresh with a fixed scope.

Delphix (Perforce)

Virtualizes SAP databases and masks them at database level. A connector covers ECC and S/4HANA on HANA or Oracle, with an accelerator that pre-identifies sensitive fields, and the integration has been SAP-certified since 2021. See Synthesized vs Delphix.

Watch for: it works below the SAP application layer, and SAP's partner listing prices its SAP scrambling connector at USD 42,000 a year per asset.

K2view

Pulls SAP and non-SAP data into business entities and masks it in flight with consistent values. Its blog names ECC, S/4HANA, SAP HANA and BW. See Synthesized vs K2view.

Watch for: its pages do not say how it connects to SAP or which releases it supports.

Libelle

SystemCopy automates full SAP system copies from outside the ABAP stack, and DataMasking anonymises SAP and non-SAP databases with templates for R/3 and S/4HANA.

Watch for: SystemCopy makes full copies rather than subsets, and masking works at database level.

Broadcom Test Data Manager

Brings masking, subsetting and synthetic generation to S/4HANA projects through database connections, alongside its wide non-SAP and mainframe coverage.

Watch for: it works at database level, not through the SAP application.

GenRocket

Generates synthetic SAP data and loads it into S/4HANA through OData and REST APIs, or produces CSV batch files.

Watch for: it generates data rather than copying and masking production.

What are the best SAP test data tools?

Inside SAP: Qlik Gold Client, SNP Test Data Organizer, Velvet Mind Data Refresh Operator and add-on suites from SAP specialists, plus SAP TDMS on ECC. Outside SAP: Synthesized, Delphix, K2view, Libelle, Broadcom and GenRocket. Add-ons suit SAP-only landscapes run by Basis teams; tools outside SAP suit teams that want nothing installed in SAP, generated data, or the same values in non-SAP systems.

What replaces SAP TDMS on S/4HANA?

SAP has not released TDMS for S/4HANA. Teams use an add-on such as Qlik Gold Client or SNP Test Data Organizer, Velvet Mind's tool on S/4HANA 2023 and later, or a platform outside SAP such as Synthesized. See SAP TDMS alternatives.

Do I need to install anything in SAP to get masked test data?

Not always. Add-ons such as Qlik Gold Client are installed in each SAP system by transport. Synthesized runs outside SAP and reads through OData or a read-only HANA user, and database-level tools such as Delphix and Libelle work on the database underneath.
