2. Informer 4: Creating and Using Functions
Presenter: Sarah Rodger
Informer Support Specialist

3. I4: Why Functions? Avoid… Easier for end users
Reduces need for copy-pasting code
Consistent results/everyone does it the same way
Make changes in one place instead of each report

4. I4: How to Create Functions
Need JavaScript knowledge
Mappings > Functions > Add Function
Almost same code as calculated script columns except:
Pass Parameters
Use Return statements (missing returns are the #1 mistake)

5. I4: Function Parameters
Use Parameters in the place of Column Aliases
Specify the Parameter’s Data Type
Label: a prompt to the user for parameters

6. I4: Function Error Checking
Provide error checking
Check for null values
Check for valid ranges
You can’t be sure what users will pass in via the parameters
