Using List of values to control flow of workflow

Hi all, recently i had a requirement to enable and disable Email notification in a workflow depending on some flag or user provided value.
To achieve this we used LOV to conditionally control the notification flow.
We used the following step.

1.Create a LOV type say ENABLE_EMAIL_NOTIFICATION.

2.Set Display name to TRUE and parent LIC to TRUE.

this value TRUE will be used as a conditon to execute the process.

Now in the workflow create a decision step and in the condition branch add the following condition.

Lookupvalue(ENABLE_EMAIL_NOTIFICATION,"TRUE") = "TRUE"

this expression takes input lov type and parent lic and get the Display value, so the condition executes only if value of LOV is TRUE.

Hope this was helpful.
