      SlNo = "1",
      IsServc = "N",
      PrdDesc = "Computer Hardware - Keyboard and Mouse",
      HsnCd = "320504",
      Qty = 25,
      FreeQty = 0,
      Unit = "PCS",
      UnitPrice = 200,
      TotAmt = 5000,
      Discount = 0,
      PreTaxVal = 0,
      AssAmt = 5000,
      GstRt = 18,
      IgstAmt = 900,
