XML Tracer 
This action is used to help debug or track transaction execution.
This action allows you to define an XML file path to log information to when the transaction runs. If the file already exists, it appends information to the files. If it does not exist, a new file is created. The Internet Guest Account user and SYSTEM accounts need read, write, and create privileges for the directory where you want to create the output file.
This action can be inserted anywhere in your transaction. To move data into the trace file at runtime, map a specific value or expression to the Message property. You can organize the messages by category. You can add all output messages to a single file or to many separate files. The output format is standard SAP Manufacturing Integration and Intelligence (SAP MII) XML which means the output can be used as an input to a visual component or sent to another transaction for consumption.
