When I joined the SAP finance team in 2012, the FSCM (Credit, Collection, and Dispute Management) project was already underway, and the go-live followed shortly thereafter. Initially, the old and new credit management systems were implemented in parallel. Over time, more and more companies migrated from the old to the new system, and two distinct approaches emerged: a lite version and a full version. The lite version offered a less detailed range of functions?for example, external ratings were not integrated, and the formula calculations were simplified. For the projects, I was involved in the design, customization, go-live, and support for various companies. In addition, I developed several custom transactions to enhance the module's efficiency for business users. Examples include:

• Master Data Analysis: This transaction provides users with a quick and comprehensive overview of FSCM data. Based on an advanced selection, the output columns are displayed dynamically, enabling efficient identification of business partners that require adjustments.
• Mass Upload and Update Transactions: These transactions offer the business a streamlined method to perform bulk changes to data such as ratings and additional information. One transaction, in particular, allows for the upload of insurance data, with the option to automatically update the business partner or customer information based on the revised insurance details.

Over the years, I have provided comprehensive support across a wide range of finance processes and systems, ensuring smooth operation and continuous improvement. My experience spans extensive customization, the implementation of various programs, BADIs (Business Add-Ins), custom extensions, and the development of specialized interfaces designed to enhance the efficiency and effectiveness of the finance department. I am dedicated to applying standards, and continuously adapting to evolving business needs to deliver robust and scalable solutions.

Throughout the years, I contributed to various support and enhancement package upgrade, including SPDD, SPAU/SPAU_ENH, testing, note implementation, and post-go-live support. The most recent upgrade I contributed to was the migration from S/4HANA version 2021 to 2023.

I participated in the S/4HANA migration of our main system, which was successfully completed in 2025. I primarily contributed to migrating custom code and the business partner concept?encompassing customer, supplier, and employee roles. In addition, I reviewed and optimized coding practices, especially regarding BAdIs, to enhance FSCM functionality. For example, while FI commitments were previously retrieved from specialized UKM tables, they can now be directly accessed from FI data. Furthermore, I managed the migration of the KPSC Classifier add-on and its associated systems, such as the browser interface and e-invoice interface. In the S/4HANA environment, the new settlement management process was also integrated into the KPSC Classifier.
