In SAP Cloud Integration, the Trace log level is specifically designed for detailed troubleshooting. When enabled, it temporarily stores the message payload at various points as it moves through the integration flow. This allows developers and administrators to inspect the message content after each processing step to understand how the data is being transformed or processed. The trace data, including the payload, is available for a short period (typically 10 minutes) after the message has been processed, providing a granular view of the integration logic's execution.

A. Error: This level only captures information when an exception or failure occurs during message processing. It does not log the payload at successful intermediate steps.

B. Debug: The Debug level provides more detailed processing information than Info, but it does not include the message payload at each step. It is for tracking the flow logic, not the data content.

D. Info: This is the default log level and provides high-level information, such as the start and end of message processing, but it does not log the payload at specific steps.

SAP Integration Suite Documentation: "Setting the Log Level"

Section: Monitoring Message Processing

Content: The documentation explicitly states: "To be able to view the message content at the single message processing steps

set the log level to Trace. The trace is kept for a certain time period (10 minutes) and is then automatically deleted." This directly confirms that Trace is the required level for examining the payload at specific steps.

SAP Integration Suite Documentation: "Monitor Message Processing"

Section: Log Levels

Content: This section details the different log levels available. It describes Trace as the most verbose level

which includes the message content (payload and headers) at different points in the integration flow

making it suitable for in-depth debugging. It contrasts this with Debug

which offers detailed logs without the message content

and Info and Error

which are less detailed.
