The document describes three case studies demonstrating integration scenarios using SAP Cloud Platform Integration. The first case study involves sending a SOAP message containing a tweet to SAP CPI, filtering the tweet text, and sending it to an email. The second case study fetches employee data from an OData system, enriches it with product details, and transfers it to an FTP server. The third case study retrieves a text file from an FTP server, converts it to XML, routes it to either another FTP server or email depending on plant code values. All case studies successfully achieved their objectives of transferring and transforming data between different systems.
