Which of the following strings represents a substitution variable?

Which of the following strings represents a substitution variable?

• A. T#|CVTime|
• B. T#CVTime
• C. |T#CVTime|
• D. T#!CVTime!

Answer: (A)

In OneStream, a substitution variable is written with a T# prefix and the actual variable name enclosed in vertical bars, like T#|CVTime|. The bars around CVTime mark the exact variable being substituted, and the T# signals that this is a runtime variable to be replaced with its value. This pattern—T# followed by |VariableName|—is what makes it a substitution variable. So the string that begins with T# and then |CVTime| fits the standard syntax precisely. Dropping the bars after T# (T#CVTime) isn’t the correct delimiter for a substitution variable, wrapping the entire token in bars (|T#CVTime|) treats the whole thing as literal text rather than a variable, and using exclamation marks (T#!CVTime!) uses a different, nonstandard delimiter.
