In short: what is SAP RE-FX?

SAP RE-FX (Flexible Real Estate Management) is SAP's solution for managing real estate and lease contracts. It holds the real estate the company owns, leases in or leases out, together with the related contracts, in SAP, and manages rent accruals, payments, rent increases and accounting entries in integration with SAP FI and CO.

One of the main topics bringing RE-FX onto the agenda today is IFRS 16. In a properly configured RE-FX/Contract and Lease Management setup, the IFRS 16 valuations of the lease liability and the right-of-use asset can be calculated from contract data. This calculation is not automatically available in every RE-FX implementation; it requires Contract and Lease Management valuation configuration, accounting principles and the relevant licence and scope.

The SAP Real Estate Management solution creates value for the retail, shopping centre, banking and real estate investment trust (REIT) sectors and enables the real estate life cycle to be managed end to end. With this solution, lease contracts, rent escalation rates, ownership structure, maintenance and repair, and construction processes can be managed from a single centre, fully integrated with SAP modules.

Key concepts in SAP RE-FX: master data and contracts

RE-FX models a real estate portfolio on two layers: the property itself and the contracts relating to it.

  • Business entity, land and building: These define the management structure of the portfolio and the physical assets, for example a shopping centre, a head office building or a logistics warehouse. Land and buildings sit under the business entity.
  • Rental object: The object that is leased out or leased in, linked to land and buildings, such as a store, an office floor, a branch, an ATM space or a car park.
  • Contract: A separate transactional object associated with rental objects; it is not part of the master data hierarchy. The parties, term, rent and service charge conditions, payment frequency, and escalation and indexation rules are held in the contract, and a contract can be linked to one or more rental objects. There can also be scenarios with assets that have no contract or are linked directly to a contract.
  • Tenant and landlord roles: Contracts in which the company is the tenant (branch, store, office, warehouse) and those in which it is the landlord (shopping centre, housing, office) are managed in the same system, through different processes.

Contracts are integrated with SAP FI and CO: depending on configuration, periodic rent postings flow automatically to accounting and to the relevant cost centre or profit centre. Maintenance and repair and construction processes can be linked to SAP's maintenance and project modules.

The SAP real estate solution in banking

Starting from branch establishment investment, project planning, cost and schedule tracking, the tracking of branch, ATM and office lease agreements, space management, rent escalation and payment processes can all be handled from one centre. Management reporting can also be set up with SAP Analytics Cloud or existing BI tools; this depends on integration and licence conditions.

The SAP real estate solution in retail, shopping centres and REITs

  • Tracking of variable, turnover-linked leases
  • Shopping centre, housing, residence and office leasing plus maintenance and repair management
  • Tracking of sub-lease and dealer-support lease agreements
  • Portfolio management integrated with the SAP FI and CO modules

IFRS 16 and SAP RE-FX: from lease contract to balance sheet entry

Since 1 January 2019, IFRS 16 (TFRS 16 in Türkiye) has required lessees to recognise lease contracts on the balance sheet, apart from exemptions such as short-term and low-value leases. For companies with hundreds or thousands of contracts, this turns lease tracking into a regular accounting calculation process.

In SAP RE-FX, this process is built on contract data:

  • Contract and conditions: The term, rent amount, payment schedule, and escalation and indexation rules are defined in the contract.
  • Valuation: Using the valuation rules assigned to the contract, the present value of future lease payments is calculated and the lease liability is determined. The initial measurement of the right-of-use asset is not always equal to the lease liability alone; prepayments, initial direct costs, lease incentives and restoration obligations can affect this amount.
  • Fixed asset integration: Depending on the scenario and configuration, the right-of-use asset is tracked and depreciated in asset accounting (FI-AA).
  • Periodic postings: Interest expense, the reduction of the liability through lease payments, and depreciation are posted periodically.
  • Changes: For changes such as a term extension, an index-linked rent increase or early termination, a remeasurement is performed on the basis of the valuation date and conditions that comply with IFRS 16 rules, and the difference is posted. However, not every index-linked increase automatically triggers a remeasurement.

IFRS 16 compliance therefore depends directly on the accuracy of contract data: if contracts are held in a scattered or incomplete way, the result will not be reliable, however automated the calculation is. Where the rent expense in the statutory books under the Tax Procedure Law (VUK) and the IFRS 16 entries need to be tracked side by side, this distinction is resolved within the same structure through the design of ledgers and valuation areas.

An example from practice: 50,000 lease contracts on a single SAP platform

At one of Türkiye's leading telecommunications companies, Montag moved around 50,000 lease contracts to SAP Real Estate Management. At the end of a six-month first phase, contracts spread across different locations, facilities and operational sites were being managed centrally in a single system, together with their contract conditions and related processes.

In the second phase, the same infrastructure was extended to meet IFRS 16 requirements. Holding the contracts in SAP in a structured, central way laid the foundation for running IFRS 16 postings and reporting from the same data source.

This example shows the right sequence for high-volume portfolios: first move contract data into a single, reliable structure, then build the accounting standard's calculations on top of that structure. For details of the project, see the 50,000 lease contracts case study.

What to clarify before starting an SAP RE-FX project

In RE-FX projects, most of the time goes not on system configuration but on understanding the contract portfolio and preparing the data. Clarifying the following points at the outset speeds up the project:

  • Contract inventory: How many contracts are there, and where and in what form are they held? How will missing or conflicting information be completed?
  • Roles: Is the company mainly a tenant, a landlord, or both?
  • Rent conditions: Are increases at a fixed rate or index-linked? Are there special conditions such as turnover rent, service charges or deposits?
  • IFRS 16 policies: Which contracts meet the definition of a lease, and which fall outside the scope of IFRS 16? Which exemptions will be applied, how will the discount rate (incremental borrowing rate) be determined, how will lease components be separated, and how will option periods be assessed?
  • Transition and opening values: What will the transition date be, and how will the opening values of existing contracts be determined and loaded into the system?
  • Accounting structure: To which accounts, cost centres and profit centres will postings go, and how will statutory book and IFRS entries be kept apart?
  • S/4HANA timing: In S/4HANA on-premise and Private Edition, the supported solution for real estate management is RE-FX; the old “classic RE” is not supported in S/4HANA. On the S/4HANA Cloud Public Edition side, the Contract and Lease Management scope and the related scope items are used, so each edition should be assessed separately. If classic RE is in use or an S/4HANA migration is planned, the real estate scope should be addressed together with that roadmap.

The answers to these questions determine whether RE-FX becomes merely a contract archive or a reliable decision-making tool for finance and management.

How Montag supports SAP RE-FX and IFRS 16 projects

Montag designs central, SAP-based structures for managing real estate, lease contracts and right-of-use assets that fit companies' operational and financial needs. Contract, payment, indexation and reporting processes are brought together in a single system; the lease liability, right-of-use, depreciation and interest processes under IFRS 16 are part of this structure. For details of the scope, see our real estate and IFRS 16 services.

Organisations that want to track lease liabilities and contract maturities alongside other financial indicators on a single screen for senior management can look at the CFO Reporting Cockpit package.

Frequently asked questions

What is SAP RE-FX?

SAP RE-FX (Flexible Real Estate Management) is SAP's solution for managing real estate and lease contracts. It manages the real estate the company owns, leases in or leases out and the related contracts; when properly configured, it produces rent accruals, payments, increases and accounting entries in integration with SAP FI and CO.

Does SAP RE-FX support IFRS 16?

Yes, but this requires the relevant Contract and Lease Management (CLM) and valuation functions to be configured. For contracts signed as a lessee, the lease liability and the right-of-use asset are calculated and posted according to the valuation rules; the amount of the right-of-use asset is not limited to the present value of the lease payments. Interest, depreciation and remeasurement entries for changes are generated periodically. The reliability of the result depends on the accuracy of the contract data.

Which modules does SAP RE-FX integrate with?

RE-FX integrates with SAP FI for accounting entries, with SAP CO for cost centre and profit centre reporting, and with asset accounting for right-of-use assets. Maintenance and repair and construction processes can be linked to SAP's maintenance and project modules. The scope of the integration depends on the system architecture and configuration.

What is the difference between tenant and landlord contracts?

In tenant contracts, the company pays rent; payments and IFRS 16 calculations for the premises it leases, such as branches, stores, offices or warehouses, come to the fore. In landlord contracts, the company collects rent; invoicing, service charge and turnover rent processes matter in shopping centre, housing and office portfolios. IFRS 16 sets out different accounting rules for the lessor than for the lessee, so the accounting design for the two roles is handled separately. RE-FX can manage both roles in the same system.

Can SAP RE-FX be used in S/4HANA?

Yes, but the answer depends on the edition. In S/4HANA on-premise and Private Edition, the supported solution for real estate management is RE-FX; the old classic RE solution is not supported in S/4HANA. In S/4HANA Cloud Public Edition, the Contract and Lease Management scope is used; the differences between editions and scope items should be assessed separately. Companies planning an S/4HANA migration are therefore advised to include the real estate scope in the migration roadmap from the outset.
