I tried to implement a retargeting in perspective.  
So I wrote in a button the following code.

```auto
def runAction(self, event):
	system.util.retarget("UserDocument")

```

When I click on this button I get the following error:

`AttributeError: 'com.inductiveautomation.ignition.common.script.Imm' object has no attribute 'retarget'`

tnx in advance

Look at the documentation - [system.util.retarget - Ignition User Manual 8.0 - Ignition Documentation](https://docs.inductiveautomation.com/display/DOC80/system.util.retarget)

Underneath the `Scope` section it will tell you where you can call this from -

You cannot use this in Perspective, only vision.

To navigate to another perspective project, you need to navigate to the URL of the other project.
