Guidelines for Locking Templates
A template can be used with one or more services on the Integration Server. Currently, you cannot lock a template as an entity, only the service to which it is attached. Following are considerations for working with templates in a cooperative development environment.
To create or edit a template for a service, you must have the service locked.
The template for a service can change without your knowledge. Since a template can be attached to one or more services, keep in mind that a shared template can change without your knowledge. For example, if your template is attached to a service that another user locks and edits, that user can change your template.
