One or several Qlik Sense fields can be dropped from the data model, and thus from memory, at any time during script execution, by means of a drop field statement.
Information noteBoth drop field and drop fields are allowed forms with
no difference in effect. If no table is specified, the field will be dropped from all tables where
it occurs.

Drop fields fieldname { , fieldname2 ...} [from tablename1 { , tablename2 ...}]
Examples:
