Groovy - Script

Introduction

Groovy Script is an important component in the SAP Integration Suite, especially in the place of SAP Cloud Platform Integration (CPI). It's a dynamic scripting language for the Java platform that enhances the productivity of integration developers.

Purpose: Groovy Script is used to implement custom logic during the integration process or mapping. It provides flexibility to manipulate messages, transform data formats, and handle complex integration flows.

Integration: It seamlessly integrates with Java, allowing developers to use existing Java libraries and frameworks in their scripts.

Features: Groovy offers features like easy-to-read syntax, error handling, and native support for XML and JSON, making it ideal for integration jobs.

Use Cases: Common use cases in SAP CPI include message mapping, data transformation, content enrichment and dynamic routing.

Why Groovy Script.?

• In the place of Groovy script, you can choose Jave script also. But Groovy is built on Java Platform and allowing seamless integration with Java libraries and functionalities, crucial in Java-heavy SAP environments.
• Groovy has excellent built-in support for XML and JSON, simplifying parsing and manipulation of these data formats in integration processes.
• Groovy provides superior error handling, especially useful in managing integration-specific exceptions.

Common use cases..

• Dynamic Header and Property manipulation
• Content transformation like XML to JSON, XML to CSV or vice-versa
• Conditional Logic
• Payload Enrichment or cleanup
• Custom Logging
• Data Mapping and Lookup
• Custom Error Handling
• Signature Generation
• Date and Time Calculation
• Complex math calculation

Build a simple flow and place Groovy script step in iFlow and copy/paste the following script..

import com.sap.gateway.ip.core.customdev.util.Message

 

def Message processData(Message message) {

    //code here

    message.setBody('Hello World')

    return message

}

Then, deploy the flow and test it.
