Material Workbench Query Logic

What's main code logic while performing query in material workbench form(INVMWBIV.fmb).

 

Key File:
INVMWBIV.fmb
INVMWQMB.pls - INV_MWB_QUERY_MANAGER
INVMWCTB.pls - INV_MWB_CONTROLLER

Key Table:
MTL_MWB_GTMP
mtl_onhand_quantities_detail
=====================
First Delete All records from MTL_MWB_GTMP.
DELETE FROM MTL_MWB_GTMP(Happen at INV_MWB_CONTROLLER.initialize)
INV_MWB_CONTROLLER.Event
|-INV_MWB_CONTROLLER.initialize
=====================
INV_MWB_CONTROLLER.initialize Call inv_mwb_query_manager.initialize_xxx procedure to do initialization.
inv_mwb_query_manager.initialize_union_query;
inv_mwb_query_manager.initialize_onhand_query; --Build MOQD select statement
inv_mwb_query_manager.initialize_inbound_query;
inv_mwb_query_manager.initialize_receiving_query;
=====================
Then retrieve records from mtl_onhand_quantities_detail to insert mtl_mwb_gtmp. Where clause depend on user's condition on query find form.
INSERT INTO mtl_mwb_gtmp (PO_RELEASE_ID,
                          RELEASE_LINE_NUMBER,
                          .....
