Is there a specific role needed for a user to approve invoices?

Summary:

We have 2 invoices that did not route to the requester for approval. Instead, they routed to FUSION_APPS_CRM_SOA_APPID and FUSION_APPS_PRJ_ADF_APPID.

Content (please ensure you mask any confidential information):

The requesters for these invoices do not have any Oracle roles. However, our understanding is that there aren't any required roles to approve invoices from the email notification. Is there a specific role required to approve invoices? If so, which roles/privileges? If not, why didn't the invoices route to the correct requester? Thanks.
