How To Query Approval Group and Approval Assignment Details For iProcurement And Purchasing Users

How can Approval Group and Approval Assignment details be queried from the database for iProcurement and Purchasing Users?

Solution
Use the Job Based query below when Employee Supervisor job based approvals are used, or Use the Position
Based query below when Position Hierarchy position based approvals are used.  The query results will show the approval list / approver list based on the job / position of the employees.

Note1:  Enter the operating unit org_id value, and specify either the User Names or the Employee IDs (comma separated). 
Note2:  The query is currently setup for Approve Purchase Requisitions; change the
pcf.CONTROL_FUNCTION_NAME value to run the query for other approval types;
