Modern business processes such as procurement, production, sales, service, finance, controlling, and human resources are highly interconnected and characterized by numerous interfaces, dependencies, and dynamic integration points. Consistent master data usage and close cross-functional collaboration are essential to meet time, cost, and quality objectives.
SAP provides an integrated solution portfolio that supports these end-to-end business processes based on modern technologies and evolving business requirements. Due to the breadth and continuous evolution of the SAP portfolio, gaining an initial overview can be challenging. The objective is therefore to offer a structured understanding of SAP process terminology, integration concepts, and corresponding solutions.
