The Challenge


Consolidation Under One Umbrella

Shared service: combining 3 SAP silos under 1 solution.

Enter SAP

Centralizing Systems to Run Simple

A governmental directive to standardize financial reporting and the need to consolidate financial data from several SAP ERP instances thanks to recent corporate acquisitions and management changes urged Türk Telekom to seek out the help of SAP.

Our main aim is to combine all of the distributed ERP systems into one centralized system. — Doruk Korkusuz, head of the financials practice, SAP Turkey

Enter SAP: The SAP Experience

A Sidecar Approach

Rather than reconfigure all of the existing systems into one, SAP S/4HANA Finance is being implemented as a "sidecar", allowing Türk Telekom to continue using its existing database. The team implemented SAP S/4HANA Finance on premises rather than in the cloud to adhere to regulatory restrictions. It currently functions as a central accounts payable, accounts receivable and general ledger system, consolidating data from the acquired companies.

Many problems solved with one Run Simple solution

Delivering on a Run Simple Promise

The new simpler processes implemented with SAP S/4HANA Finance eliminate unnecessary workload, provide more flexibility, provide greater clarity and transparency into financial data and significantly cut processing time by days.

Better Business: Benefits

An Umbrella Keeps Company’s Financials Covered

The innovative technology solutions offered by SAP provide Türk Telekom with the flexibility to adapt to organizational and market changes. New governmental regulations have recently been implemented which restrict and constrain financial reporting, but with SAP S/4HANA Finance, it’s easy for Türk Telekom to meet these expectations easily and seamlessly.

An SAP umbrella program unites several disparate solutions.

Better Business: Run Simple

Simplified Processes for Today and for Tomorrow

The implementation of SAP S/4HANA Finance has helped Türk Telekom transition from multiple ledgers to an integrated business with one software environment. They can now easily integrate business processes of other business units and are poised to speed up mergers and acquisitions as they continue to grow.

Journey Ahead

Moving Forward with SAP By Their Side

With a new system in place, Türk Telekom is looking ahead to the future. Their first aim is to complete the implementation of their road map for various arms of the company. They are eager to begin the next phase, optimizing procurement processes with solutions from Ariba®, an SAP company. They are also looking to incorporate expense solutions from Concur (now part of SAP) to streamline their expense payment process.
