SAP CPI Content Modifier: A Quick Guide

In SAP Cloud Platform Integration (CPI), the Content Modifier is a very commonly used step in an integration flow (iFlow). It allows you to set or modify various parts of the message, such as:

Main Uses of Content Modifier

It can modify these parts of the message:

1. Message Body

   • You can set a custom body (e.g., fixed XML/JSON, plain text, etc.)

   • You can use expressions like ${property.<propertyName>} to dynamically set content.

2. Message Headers

   • Add or modify message headers.

   • Useful for routing, target system requirements, etc.

3. Message Properties

   • These are local variables used during message processing.

   • Useful for temporary storage or decision-making in the iFlow.

4. Exchange Properties (optional in advanced usage)

   • These are technical, camel-level properties (less commonly modified here).

Structure of Content Modifier

When you open the Content Modifier in CPI, you'll see four tabs:

• Message Header – Add/modify headers.

• Message Body – Replace or modify the body.

• Message Exchange Property – Not commonly used unless you're interacting with adapter-level parameters.

• Message Property – Add or modify custom properties for use in mapping, routing, etc.

Example Use Case

Scenario: Add a custom header and set a JSON body.

• Message Header:

  Name	Type	Value
  Content-Type	String	application/json

  
  

• Message Property:

  Name	Type	Value
  orderId	String	123456

  
  

Tips

• You can use expressions like ${header.<headerName>}, ${property.<propertyName>}, ${in.body}, etc.

• Properties are local to the iFlow. They are not sent to target systems.

• Headers are usually included in HTTP calls.

Happy Integration!
