This procedure call is a way for BWoH to specify a query without using SQL.
You can review the query conditions via RSRT trace options to understand what is requested from the DB.
Also, checking runtime stats for your query will deliver important information (e.g. records returned).
Finally, you could create a PlanViz trace for the procedure call.
However, there is typically not much you can do about the query in the first place, so it's questionable whether this will get you far.
