Solution Areas

Add-ons that close the gaps standard SAP® software leaves open

Three domains where regulatory pressure and operational volume meet — each delivered as a focused add-on for SAP S/4HANA®, designed for use with SAP® solutions and built on patterns proven in enterprise projects across Europe.

Jakub has designed and delivered solutions in these areas for enterprises across Europe. Jakub builds on this practical experience to create focused SAP add-ons.

RE-FX-LA SAP S/4HANA Multi-GAAP

IFRS 16 Lease Accounting Solutions

The problem

IFRS 16 requires every lease to be measured, posted and re-measured across parallel valuations. Standard SAP RE-FX-LA covers the framework, but high lease volumes, modifications, indexation and multi-GAAP reporting quickly overwhelm manual handling.

How Salsata solves it

Jakub builds add-ons for SAP S/4HANA that automate lease present-value calculations, schedule generation and re-measurement, run them as controlled batch jobs, and produce reconciled, audit-ready reporting across multiple accounting principles.

Key capabilities

Automated lease present-value and right-of-use calculations
Re-measurement on indexation, modification and scope change
Parallel multi-GAAP valuation and posting
High-volume batch processing with full logging
Reconciliation and audit-ready disclosure reporting

Suitable for

Telecommunications
Multimedia
Retail
Railways

FI SAP RE-FX DMS

Property Tax Automation Solutions

The problem

Annual property tax declarations are compiled by hand from real-estate master data scattered across many legal entities. The process is slow, error-prone and hard to audit — and it repeats every single year.

How Salsata solves it

Jakub builds add-ons for SAP S/4HANA that read property and tax master data directly from SAP RE-FX and FI, generate the required declarations, and archive everything through document management — for any number of entities at once.

Key capabilities

Declaration generation from SAP master data
Document management (DMS) integration and archiving
Multi-entity, multi-property processing in one run
Repeatable, fully auditable year-on-year process

Suitable for

Railways
Government
Energetics
Retail

ABAP eIDAS SAP S/4HANA

E-Signature Integration Solutions

The problem

Documents generated in SAP — contracts, approvals, bank instructions — are still printed, signed by hand and re-scanned. The break in the digital chain is slow, hard to audit and legally fragile.

How Salsata solves it

Jakub builds add-ons for SAP S/4HANA that connect document and approval flows directly to qualified trust service providers, so qualified electronic signatures (eIDAS) are applied inside SAP — with a complete, tamper-evident audit trail.

Key capabilities

Qualified electronic signatures (eIDAS) inside SAP workflows
Connectors to qualified trust service providers (QTSP)
Signing of contracts, approvals and bank instructions
Tamper-evident, fully auditable signature trail
Fiori-ready signing experience

Suitable for

Railways
Government
Energetics
Telecommunications
