The client was transitioning their financial data from various legacy systems to S4 Hana. Progress on large-scale initiatives was hindered by time-consuming manual tasks and a lack of daily clarity. The client faced difficulties in managing financial data spread across multiple systems such as the Enterprise Data Warehouse (EDW), Business Warehouse (BW), SAP S4 Fiori, S4 Hana, BI, TERA, and ODW. Moreover, understanding the end-to-end data flow across these applications proved challenging, especially while considering server timings across multiple regions (AMS, EMEA, and APJ). Additionally, the validation and reporting of pre-close and post-close data flow discrepancies between software systems were both critical and complex. To address these issues, the client engaged KPMG in India's assistance in ensuring financial data accuracy and integrity, including SOX compliance during month-end and year-end closures.
