The SAS Marketing Automation 5.3: User's Guide on page 72 and 73 shows the wrong syntax for the Code node stored process keywords InSubject and OutSubject.

The correct syntax for the keywords is below:

InSubjectID=<your input subject>
OutSubjectID=<your output subject>

For example, here is how you would use these keywords to indicate that the incoming subject for your Code node is "Customer" and the outgoing subject is "Household":

InSubjectID=Customer
OutSubjectID=Household
