Into the Select Attributes operator you have many alternatives to carry out the filtration of your dataset, for example remove the missing values, or work with regular expressions.

Hi,
First you use declare missing values to make it a missing, then you can use filter examples with 'is not missing' to remove it.
Best,
Martin
