             Summary: Add/clarify why modifying/creating variables are not 
considered local changes in versioned flows
                 Key: NIFI-5677
                 URL: https://issues.apache.org/jira/browse/NIFI-5677
             Project: Apache NiFi
          Issue Type: Improvement
          Components: Documentation & Website
            Reporter: Andrew Lim


There has been some confusion over why creating or modifying variables in a 
versioned flow do not trigger local changes in the flow.

Will improve the relevant section in the User Guide 
(https://nifi.apache.org/docs/nifi-docs/html/user-guide.html#managing_local_changes)
 with the following clarifications:

Modifying doesn’t trigger local changes because variable values are intended to 
be different in each environment.  When a flow is imported to an environment, 
it is assumed there is a one-time operation required to set those variables 
specific for the given environment. 

Creating a variable doesn’t trigger a local change because just creating a 
variable on its own has not changed anything about what the flow processes.  A 
component will have to be created/modified that uses the new variable, which 
will trigger a local change.
