API that populates MTL_SUPPLY_DEMAND_TEMP (Form Name : View Supply Demand INVDVDSD)

In the View Supply Demand form (INVDVDSD), and Item Number is entered in the Query Find block, and when the Find Block is clicked the details are retrieved in the Supply/Demand details screen. The base table of this screen is MTL_SUPPLY_DEMAND_TEMP which is populated by an API when the Find button is clicked.

I have managed to identify that the API  is FND_TRANSACTION.SYNCHRONOUS and the ARG_1 parameter look likes 'INXDSD GROUP_ID=1234567 ORGANIZATION_ID=103 INVENTORY_ITEM_ID=168160 ONHAND_SOURCE=3 CUTOFF_DATE="" MRP_STATUS=1 ONHAND_FIELD=CRITERIA.TOTAL_TEMP AVAIL_FIELD=CRITERIA.AVAIL_QTY_TEMP';
