Edit Task


Back to Main Help

An Edit Task takes any Text column as input and generates one text Results column.  

Each Results column entry contains input text after one or more Substitutions are made.  Each Substitution replaces a Pattern with Replacement text.  See Using Patterns and Substitution Lists.   


In the example above, the “Normalize Description” column is generated by an Edit Task that uses the “Exam Description” column as input and makes substitutions to replace local terminology, usage and abbreviations with standard terms.   The Substitution List used by this Edit Task is shown in the Substitution List Help.

What’s Needed

To create an Edit Task, the prerequisite objects are:

·      Template – the new Task will be added to this.

·      Input Column – a text column in the Template

·      (possibly) Substitution List  – if you want to perform a list of substitutions – not needed for a single Substitution.
