How to extract requisition approval rules created in BPM as a report or CSV file.

Summary:

Requirement is to extract approval rules along with details/settings of the various stages, participants and the rulesets.

Content (required):

I have referred a document where we can extract a report on approval rules (How to extract a Report on Purchase Requisition and Purchasing Approval Rules — Cloud Customer Connect (oracle.com)), but it doesn't work when we configure the rules using BPM. I read that access to fa_fusion_soainfra tables have been provided since R13 making it feasible to extract BPM rule information, hence I wanted to know if there is any report/SQL query/any other solution to extract the approval rules.
