"Replace Missing Values Failure"

Jester87

I tried the Replace Missing Values operator in the tutorial, and it didn't seem to replace any of the null values.

For me, the process you have posted works perfectly. But did you notice that there is a break point after the Retrieve operator? That means that the process will stop after data loading and show an intermediate result. Note that the Run button is green while the process is in the breakpoint. To execute the next operators, you have to press the green Play button again.
