Get all Approvers for a Purchase Order in Position Hierarchy

<pre>SELECT position_structure_id, business_group_id
 
FROM per_position_structures_v
 
WHERE NAME = '&POSITION HIERARCHY NAME'

[/pjp]
Now we are ready to use our script which takes position_structure_id and business_group_id obtained from the above query and top position id 
for a given position hierarchy as inputs:
