When the same process variable is updated by both the input and output of a 'user input task' what will be the result? From what I have tested, the input takes precedence. As implemented in the attached photo, the initialization set in the output (setting to NULL) does not execute.

can you provide some more info about the issue and what are you trying to achieve.
JayaPrakash Ravipati Ultimately, I expect 'errMsg' to be NULL. If I do not set SaveInto for INPUT, I can achieve this, so it is probably a mistake in my implementation, but I asked the question because I wanted to know the root cause and the relationship between INPUT and OUTPUT.
