Which expression language can you use to access the content of a message in an...

In SAP Cloud Integration, expression languages are used to dynamically access or manipulate message content, headers, or properties. Let’s break it down:

Step 1: Purpose- The expression language must allow accessing message content (e.g., body, headers) in iFlow components like Content Modifier or Router.

Step 2: Evaluate Options-

A. Simple Expression Language: SAP’s proprietary language (e.g., ${in.body}, ${header.key}) designed for iFlows to access message content, headers, and properties.

B. Spring Expression Language (SpEL): Used in Spring Framework, not natively supported in SAP Cloud Integration iFlows.

C. JavaScript Expression Language: JavaScript is for scripting (e.g., in Groovy/JavaScript steps), not a general expression language in iFlows.

D. XML Expression Language: No such standard exists in SAP Cloud Integration; XPath is used for XML, but it’s not a general-purpose language.

Step 3: Use Case- In a Content Modifier, you might use ${in.body} to access the message payload, which is part of Simple Expression Language.

Step 4: Official Verification- The SAP Help Portal’s "Simple Expression Language" documentation explicitly states it’s used across iFlow components to access message content.

Conclusion: Option A (Simple Expression Language) is the correct answer.References:
