Hello ​@mtrokan,

Assuming that your objective is to add a supplier to an Approved suppliers list which is included in the purchase authorization process to be used for parts in a purchase group on a particular site, You can do this by navigating to “Approved Supplier List” page and then adding the “Approved Supplier List” header. 

Note that “Site”, “Purchase Group”, and “Auth. Routing Template” that needs to be added to complete the “Approved Supplier List” header creation, has to be defined as prerequisites before this step. 
 

Once the header is created then click “+” to add the suppliers.
 

Then users can proceed to click the “Approve” command to complete the Supplier Approval. Optionally there is a command to “Remove Approval” if required at a later stage or users mistakenly approve a supplier. 

It is important to note that under the normal process any purchase of parts that belong to a defined purchase group (attached to the respective site), which in turn are used on the list, will require authorization. However, If an organization have any suppliers that has gone through the validation process and are approved, these suppliers should be added to the list and get approved. Once they get added and approved they will then no longer need authorization.

Hope this helps!

Cheers!
