Custom-based routing is a pivotal component of modern integration strategies, empowering organizations to steer their digital processes with precision and agility. At the heart of this dynamic routing approach lies the use of operands, which act as the building blocks for creating sophisticated routing rules. These operands, ranging from simple conditions to complex expressions, grant businesses the ability to intelligently direct data and messages across diverse systems, applications, and services within their integration landscape. In this realm of integration, operands serve as the navigational compass, enabling enterprises to orchestrate seamless interactions, optimize workflows, and enhance the efficiency of their SAP Integration Suite implementations.
Within the custom routing tool, there are operands for string data type and for numeric data type. Let’s explore these two types of operands that are available in SAP Integration Suite, managed gateway for spend management and SAP Business Network, within the custom routing tool.
