====Changing, Copying & Deleting Asset Relationships===

It is possible to //change//, //copy// and //delete// an existing relationship (or set of relationships) between assets. 

To do so, open the [[detail_relationships|relationship details]] for the parent asset, and click on the //modify// (<faicon fa fa-arrow-circle-down>) button next to the particular relationship you'd like to change.

Here, you can choose from the list of relationships and settings to choose what you'd like to do with the selected relationship.

===Changing===
//Changing// the relationship allows you to swap the //type// of relationship this represents. 

Simply choose the name of the new relationship from the list, choose if you'd like this change to also follow all of the child assets, and hit 'Change Relationship'.

===Copying===

If you'd like to //copy// an existing relationship across to another, follow the same process as changing (above) but also check the **Leave Original Relationship** checkbox. 

This is very useful in some services that share paths or piplines, allowing you to define the relationship once and copy it several times.

===Deleting===

If you've made a major mistake you need to erase, you can instead //delete// relationships rather than changing them.

To do this, choose **None [Delete]** as the new relationship name.

Note that **Leave The Original Relationship** must be turned //off// - otherwise no changes will be made.

===A Note About Deleting / Changing===

When you delete or change a relationship along with it's children, you may need to be aware of exactly what happens.

The old relationship is deleted //down until it reaches the first asset with more than one parent//.

Let's imagine we have a battery backup power supply for our lighting.

**Mains** > ** Lighting Breaker A** > **Wall Switch A** > **Light Bulb**

**Batteries** > ** Emergency Lighting Breaker ** > **Wall Switch A** > **Light Bulb**

If you choose to delete the power relationship for the batteries, the system will remove the relationships between the batteries and the emergency lighting breaker, and between the breaker and the wall switch.

However, it will **not** erase the relationship between the switch and the bulb, because the wall switch has a 2nd source of power.

In this case, if you wanted to remove the 'power' relationship all-together, you'd also need to delete it from //Mains// too.
