Implementation of the MÁV CER system

Client Description

MÁV (Hungarian State Railways) is Hungary's state-owned railway company and one of the country's most significant transportation enterprises. With a history spanning over 150 years, it has developed an extensive railway network, providing both domestic and international passenger and freight transportation. The company's goals include infrastructure development, modernization of rolling stock, and improving services to offer efficient and comfortable travel for both passengers and industrial clients.

Project General Description

The introduction of the Master Data Management framework - Article Number Pre-system linked to the MÁV SAP system. The SAP system implemented at MÁV organizes the control and descriptive master data of product, service, and equipment article numbers into different views within the Material Master. This ensures the availability of constant and control data, not only for basic data but also for sales, procurement, accounting, inventory management, and even quality management.

Master Data Management

Challenge

The client requires the development of a system that allows users to quickly provide the data necessary for article operations, supported by field-level definitions. The parallel assignment of tasks will be implemented using a workflow system, which ensures that responsible parties receive email notifications about incoming tasks. With the support of the workflow, the possibility of errors decreases, processes are accelerated, and optimized task distribution is achieved.

Maintenance staff always have accurate information, while requesters receive correct feedback. The system guides users step-by-step, ensuring no administrative activities are missed, and processes remain traceable for future reference.

Additionally, an interface connection with the SAP system must be established, enabling quick, free-text article searches and checks. The system automatically executes the complex validations defined in SAP, preventing the saving of incorrect data.
