Vishal,
You can use Application_FormDataEvent to block the add.
  Private Sub Application_FormDataEvent(ByRef args As SAPbouiCOM.BusinessObjectInfo, ByRef bubbleEvent As Boolean) Handles MyApplication.FormDataEvent
    If args.BeforeAction Then
      Select Case args.EventType
        Case SAPbouiCOM.BoEventTypes.et_FORM_DATA_ADD
          ' get document form
          Dim form = MyApplication.Forms.Item(args.FormUID)
          ' get docucment matrix
          Dim matrix = DirectCast(form.Items.Item("38"), SAPbouiCOM.Matrix)
          For row = 1 To matrix.RowCount
            ' get ItemCode
            Dim ItemCode = DirectCast(matrix.Columns.Item("1").Cells.Item(row).Specific, SAPbouiCOM.EditText).String
            ' Do a query on inventory or use Company object
            ' If a line is not allowed block adding the order:
            bubbleEvent = False ' order is now blocked!!
          Next row
      End Select
    End If
  End Sub
