Using insert recordset in temporary table

But it when debugger comes to execution of this statement, AX doesn't respond and have to restart. What could be the problem...? 

    InventSum                           inventSum;
    InventDim                           inventdim;
    InventSerial                        inventSerial;
    z_RentalOrderLine                   rentalLine;
    maRentalSiteReconciliation          reconciliation;
    maItemsWithNoOpenRentalContracts    temptable;

    delete_from reconciliation;
    delete_from temptable;

    insert_recordset reconciliation (ItemId,InventSizeId,InventColorId,InventStyleID,InventLocationId,WMSLocationId,InventSerialId,z_ManufacturersSerial,z_NBV)
    select ItemID from inventSum
    join InventSizeId,InventColorId,InventStyleID,InventLocationId,WMSLocationId from inventdim
    join InventSerialId,z_ManufacturersSerial,z_NBV from inventSerial
    where inventSum.InventDimId         == InventDim.inventDimId
       && inventSerial.InventSerialId   == inventdim.inventSerialId&& inventSerial.ItemId           == inventSum.ItemId&& inventSum.Closed              == NoYes::No&&(inventSum.PostedQty + inventSum.Received - inventSum.Deducted + inventSum.Registered - inventSum.Picked) - inventSum.ReservPhysical > 0&& inventdim.wMSLocationId       == "On Rent";
