                        Dim doc As String

                            oForm.Select()
                            oForm.Freeze(True)
                            oForm.Mode = SAPbouiCOM.BoFormMode.fm_FIND_MODE
                            oForm.Items.Item("txt_ino").Specific.Value = Trim(doc)

Case SAPbouiCOM.BoEventTypes.et_MATRIX_LINK_PRESSED And pVal.BeforeAction = False
                    If pVal.ItemUID = "matrix" And pVal.ColUID = "Docno" Then
                        Dim oMatrix As SAPbouiCOM.Matrix
                        Dim doc As String
                        oMatrix = Frm.Items.Item(pVal.ItemUID).Specific
                        doc = Trim(oMatrix.Columns.Item("Docno").Cells.Item(pVal.Row).Specific.Value)
