Use case in SAP CPI

 Why Groovy is Powerful in Integration (especially SAP CPI)

SAP CPI provides many standard tools like Message Mapping, Content Modifier, etc. But real-world integrations often need custom logic, such as:

 Complex data parsing (e.g., splitting a CSV file, filtering records) 

 Custom message transformation (e.g., dynamic XML or JSON generation) 

 Header/property manipulation (e.g., set Authorization header based on token) 

 Dynamic behavior (e.g., choose endpoint URL based on some condition) 

Standard flow steps are not enough for these, so SAP provides Script Step where Groovy is used.

Example Use Cases in SAP CPI

Use Case	Groovy Script Role
Transform CSV to XML	Parse CSV line by line and generate XML format
Set CSRF Token in Header	Extract and set token for HTTP request
Filter out invalid records	Loop through records and skip based on conditions
Generate Atom XML	Build deep insert XML payload for OData
Format DateTime	Convert date formats as required by receiver

Groovy in SAP CPI gives flexibility and control when standard flow steps fall short. It enhances your ability to customize, transform, and control data and integration logic to meet complex business needs.

In Short, Groovy = "Custom logic engine" inside SAP CPI

It gives developers the power to go beyond the limitations of graphical tools. It’s ideal for: 

 Complex data manipulation 

 Dynamic behavior 

 Fine-grained control over message processing
