You may only have one approved model at any given time. 

Individual stages must be approved and leads added before you approve an entire model.

Approve

Open the Analytics area of Marketo.

Select a model from the tree.

From the Model Actions menu, choose Approve Model.

A dialog appears to confirm your choice. Click Approve.

 

Your model is now live! 

Unapprove

If you unapprove your model all of your leads are removed from the model, and their history in the model is deleted!

Open the Analytics area of Marketo.

Select a model from the tree. 

Click the Model Actions menu and choose Unapprove Model.  

In the dialog that appears, click Unapprove Model.  

 

 

 Congrats! Your model is now unapproved.

Unapproving a model removes all your leads from the model, and removes their history in the model from the lead database.
