In VA 7.4, the NotMissing operator might return an unexpected value when a parameter is not set

[AnnaBrown]

Heads up, SAS Visual Analytics Community, about a difference in the NotMissing functionality in 7.4.

There are two workarounds for this issue:

• Instead of NotMissing, use the GetLength operator to check if the parameter has a length greater than 0.
• Modify the expression to use the Missing operator instead of the NotMissing operator. The Missing operator is evaluated as expected.
