Logali Tech
Logali SAP Development Series

From the language to deployment: the modern SAP development stack

A coherent collection on ABAP Cloud, S/4HANA, Fiori, BTP, and HANA. Every code block written, assembled, and executed on a real SAP system before publication.

First things first 100% to open-hand.org

100% of every book purchase is donated to open-hand.org

This collection does not exist to generate revenue: it exists so that twenty years of knowledge serve twice. Every book, bundle, or donation in this shop is collected on behalf of open-hand.org, a nonprofit we sponsor — Logali covers the payment fee, so open-hand receives the full amount. We publish a quarterly report. This applies only to books and donations: training (subscriptions and masters) is not part of this program.

What sets it apart

Verified on real systems

Every code block was written, assembled, and executed on a real SAP system (S/4HANA 2025, SAP HANA Cloud, and Node.js projects) before publication. The outputs you see are the real system outputs.

A single common thread

The fictional company Logali Tech runs through the whole collection: you learn each technology by solving cases from one coherent business, not scattered examples.

Bilingual, written not translated

Each title is available in Spanish and English, with the correct technical vocabulary in each language. No calques, no made-up terms.

100% to open-hand.org

The full price of every purchase is donated to open-hand.org. Logali covers the payment fee; a quarterly report is published.
