By default, tasks can be related to each other using a parent/child relationship, such
as a Problem with a group of child Incidents or a Catalog Request with a group of child Catalog
Tasks.

However, it may prove useful to record exactly the nature of the relationship between the task records. When activated, the Many-to-Many Task Relations plugin allows administrators to define relationships between different
tasks.
* **[Request many to many task relations](https://www.servicenow.com/docs/V9cIBz7EfTrFimHCPNLNvQ)**   
  The Many to Many Task Relations plugin (com.snc.task_relations) is included with several plugins. You can request activation of the plugin by itself.
* **[Plugin manifest](https://www.servicenow.com/docs/20whL5GJlbV89H_VofkHgg)**   
  When the plugin is activated, the Task Relationships application is available with certain modules.
* **[Define a relationship type](https://www.servicenow.com/docs/7epv92esuWlPnHdDjhlMeA)**   
  Create type codes that define the relationship between parent and child tasks.
* **[Define a task relationship allowed from the task relationship type record](https://www.servicenow.com/docs/5ZUpe5xl3Fh5gaGYUnv0QQ)**   
  Define the Task Relationships Allowed from the Task Relationship Type record.
* **[Modify the displayed field](https://www.servicenow.com/docs/406EXSK9HXC_68SxkNN88g)**   
  The list view of the Reference Lookup defines the fields displayed in the Task Relations field and editing interface.
* **[Mark as Solution button](https://www.servicenow.com/docs/G1hJaZfV7XZaDU3XP_UFAA)**   
  The Mark as Solution button is added to the KB popup view and displayed when you search the knowledge base from a task record.
* **[Task relationships with UI actions](https://www.servicenow.com/docs/66CdM7e8LG4J9pe65gKNdg)**   
  After defining task relationships, you can use UI Actions to define the task relationship when a new task is being created from an old task.
