To prevent users from making changes to a workflow that affect other users of the
system, workflows must be checked out before they can be edited.
Only one user can check out a workflow at a time. When a workflow is checked out, changes apply
only to the user who has the workflow checked out. Other users can continue to use the published
workflow. After the changes are complete, the workflow can be published so that it is available
to all users.
Note: Because each workflow has a unique sys_id, different workflows can have the same
name. This is typically expected in a domain-separated environment where users in different
companies cannot see each other's workflows because they are in different domains. However, this
can lead to confusion in other environments. In general, give each workflow a unique name to
prevent workflow designers from making changes to the wrong workflow.
When a new version of an existing workflow is published, the changes are not applied to running
workflow contexts. Any currently running workflow context continues using the workflow version
that was available when the workflow started. The next time the workflow runs, it uses the
updated, published version.
