Order Approval Rules – Mapping Approval Steps to Approval Groups (Data Base Tables)

We are building a report to identify the user groups responsible for approving orders.

Approval stages are defined using Manage Order Approval Rules, and approval groups are stored in
fa_fusion_soainfra.wfapprovalgroups.

We are trying to identify the database table(s) or object(s) that associate the order approval workflow steps with the corresponding approval groups assigned to each step.

Any insight into the relevant Fusion database objects would be appreciated.
