One way.......create an inline table at the beginning of your script that contains the column name TestType and the keywords you want to exclude (this could also be another spreadsheet or database table if you want users to maintian the list of keywords). Then in your existing script, use "Where Not Exists(TestType)" to exclude data matching the keywords you loaded.
Sorry, Im not very skilled with Qlikview code, and not sure at all about inline tables.
Is there not as easier piece of script to use that I can add under the code that's already there to only show data when the "TestType" field is blank? Or when there is certain words in it?
Similar to how the "Where Year > 2010" works? I've tried changing this around already though but can't figure it out.
