New Idea - Reference Data Elements | Automatically Update Names of Data Elements
As mentioned before Automatically Update Names of Data Elements Used in DTM Rules with 10 votes by user: @jon_kranz
PROBLEM
Changing the name of a Data Element does not automatically update the name of the same element when it is used in any Launch rule.
SUGGESTED SOLUTION
IF the name of a Data Element has been updated
AND that same Data Element is referred elsewhere within Launch (be it a rule or installed tool or anywhere else it is used)
THEN system will automatically update the name of the Data Element anywhere it is used.*
*Note: This solution would exclude areas where custom scripts are permitted. My naive assumption is that having the system change custom scripts would be a very bad/problem-causing idea.
Adding support to update _satellite.getVar('dataElementName'); should be in this scope as well, I don't see why this would cause issues since its a simple string replacement.
Thanks for listening.
