Restrict using supplier, if all approval steps are not approved

Hi,

I have attached an approval routing for supplier. Purpose is to get the approval from certain set of people for creating the supplier. 

How this actually works ? If all the approval steps are not approved, will the system give any error message ? If  all the approval steps are not approved , will the system not allow to use that supplier in a purchase order ? 

Or is it just a manual indication ? 

(note: this is IFS cloud 22R1)

kind regards,

Yashodha.
