itemid = "20 MM RMC";
// take a combination of dimension , against which you want to find the stock
inventDim.InventLocationId = "GW";
//Set the flag for the selected dimensions as active.
inventDimParm.initFromInventDim(inventDim);
//initialize the inventonhand with item,dimension and dim paramter
inventOnHand.parmItemId(itemid);
inventOnHand.parmInventDim(inventDim);
inventOnHand.parmInventDimParm(inventDimParm);
// Retrieve the onhand info
info(strfmt("Available Physical: %1",
inventOnhand.availPhysical()));
info(strfmt("On order: %1",inventOnhand.onOrder()));
