RE-FX, CLM and Planon
The reordering of SAP's real estate architecture — current state and target picture

The core shift: RE-FX remains, innovation moves on

SAP RE-FX (Flexible Real Estate Management) is not being retired, but it is also no longer being developed strategically. The module is effectively in maintenance or stability mode with no substantive innovation roadmap. Mainstream maintenance for classic SAP ERP 6.0 (EHP6–EHP8), on which many existing RE-FX landscapes run, ends on 31 December 2027, with optional extended maintenance until 31 December 2030.¹² For the S/4HANA embedding of RE-FX, support is indicated until at least 2040, alongside a possible successor solution named SIRE (SAP Intelligent Real Estate).³⁴ Further development of master data management, service charge settlement or rent adjustment within RE-FX no longer takes place.²³

SAP's strategic future in the real estate domain lies in the combination of SAP Contract and Lease Management (CLM) for commercial processes and Planon for operational facility and space management. This realignment rests on a partnership between SAP and Planon, in which Planon is now positioned as an SAP Solution Extension.²⁵ For existing customers this creates no obligation to migrate immediately, but it does create a medium-term requirement to define a target architecture.

SAP RE-FX and SAP CLM: the functional boundary

CLM is built technically on RE-FX and inherits its core logic for IFRS 16-relevant lease-in contracts, but does not cover the full functional scope. The central architectural difference lies in the cut: RE-FX models the complete real estate architecture including integrated space management, while CLM concentrates on commercial contract processes and delegates space and room administration to Planon.⁶⁷

Parallel operation of both solutions is possible and sensible in certain constellations: RE-FX for real estate leasing, CLM for other lease contracts, where both contract types occur within the same group.⁸

Planon Standalone and SAP Real Estate and Facilities Management by Planon

The distinction between the two variants is among the most frequent sources of confusion in the market, because Planon's positioning within the SAP landscape has changed several times in a short period. The joint solution was originally announced in May 2023 as “Planon Real Estate Management for SAP S/4HANA” and published in March 2024 as an SAP Endorsed App in the SAP Store.⁹¹⁰ In January 2026 it was upgraded: the Endorsed App became an SAP Solution Extension under the product name “SAP Real Estate and Facilities Management by Planon”.³⁵

The difference is more than nomenclature. As a Solution Extension, the solution has passed SAP's premium qualification process and is available directly through SAP sales and reseller channels including SAP support services, rather than merely being listed as a recommendation via the Store.¹⁰ The integration architecture connects Planon's real estate and facility management processes to the S/4HANA financial backbone via SAP Contract and Lease Management. The integration is available for S/4HANA Cloud Public Edition (from 2402), S/4HANA Cloud Private Edition (2023, FPS 1+) and S/4HANA on-premise (2023, FPS 1+).¹¹

“Planon Standalone”, by contrast, denotes Planon's independent IWMS/CAFM platform outside the SAP integration. It can still be used independently, but then lacks the native connection to SAP financial processes.⁹

In the integrated variant, responsibilities are clearly separated: real estate and facility management processes run in Planon, while the associated financial processes — cost allocation, cost distribution, and cost and revenue reporting — remain in SAP S/4HANA.⁹ In June 2026 Planon additionally extended the platform with an integration to Microsoft Places for hybrid workplace scenarios, and with “Planon for Data Centers” for critical facility operations.¹⁰

IFRS 16 after the shift

IFRS 16 compliance is fully covered in both worlds, but differs in governance. RE-FX continues to offer comprehensive standard functions: classification of contracts as leases, automatic determination of right-of-use assets and lease liabilities, and IFRS 16-compliant reporting. This functionality was integrated into RE-FX in 2018 and permits balance sheet capitalisation of lease-in contracts where they are relevant for measurement.⁶⁸

CLM inherits the same IFRS 16 measurement logic, being built technically on RE-FX, but supplements it with direct integration into SAP financial accounting (Universal Journal), standardised IFRS 16 reports, and an integrated treatment of contract modifications.⁷¹²

On the question of which component carries which starting position, a division emerges in practice. Organisations already using RE-FX for IFRS 16 and required to represent multiple accounting standards (IFRS, HGB, US-GAAP) in parallel have substantive grounds to remain on RE-FX for the time being.⁸ Organisations building a central, highly automated contract administration without an existing RE-FX licence, or migrating to S/4HANA Cloud Public Edition, are directed to CLM, since RE-FX is not available there.⁷

In a migration towards CLM plus Planon, the IFRS 16 measurement rules remain in the SAP financial core, while operational master data and space information move to Planon. Relevant for migration projects: existing lease-in and lease-out contracts, including opening balances and obligations under IFRS and US-GAAP, must be actively rebuilt in the new CLM system, since measurement rules are not transferred automatically by the migration cockpit.⁶⁹¹²

SAP Solution Extension: what the status signifies

An SAP Solution Extension is a solution from an exclusively selected independent software partner that SAP itself sells and supports, although the code does not originate from SAP.¹⁰ Compared with an Endorsed App or an unaffiliated third-party solution, four practical differences follow.

Procurement takes place through the regular SAP price list and sales process, or the SAP Store, rather than through a separate contracting party.¹⁰ Quality assurance comprises SAP certification, architecture reviews and integration testing.¹³ Support forms part of the offering, which shortens escalation paths for organisations with existing SAP support agreements.⁹ And investment security follows from the status identifying the solution as a component of SAP's target architecture rather than an optional addition.¹⁴

For existing customers on classic RE-FX, Planon's Solution Extension status means concretely that the route to a cloud-capable target architecture runs through two separate but officially integrated SAP products — CLM for the financial processes, Planon for operations — and not through a monolithic successor solution.²⁹¹⁰
