Embedding Templates
You can reuse tasks from one template in another by embedding a template into another template. When you schedule tasks for a template, tasks for embedded templates are also scheduled.
For example, the Quarterly close process may be the same as the Monthly close process with some additional quarterly-only tasks. Instead of copying the Monthly template, you can specify that the Quarterly template embeds the Monthly template so if you change the Monthly template, you do not need to update the Quarterly. When you generate a schedule from the Quarterly template, the schedule includes the tasks from the Monthly template.
Note:
Only one level of embedding is possible. For example, if Template A is embedded in Template B, then Template B cannot be embedded in another template.
