Could you please check attached process? There are missing values in the data set. Although we see those missing values in the meta data information in the output port of the multiply operator, in the process result those missing values are replaced by the imputing operator's outcomes.

    Hi,

    technically, it's the "Impute Missing Values" operator that is buggy. It changes the underlying data behind the scenes which is bad. Until this is fixed, you can work around this by adding a "Materialize" operator after the "Multiply" operator to get a fresh copy of the actual data:
