Problem with Link Button

Question

Hi
I've got a linked button in a column within a matrix that shows Sales Order Document Numbers. I've set it to link to the Sales Order form using the following code:
        oColumn = oColumns.Add("OrderNum", SAPbouiCOM.BoFormItemTypes.it_LINKED_BUTTON)
        oColumn.TitleObject.Caption = "Order Number"
        oColumn.Width = 200
        oColumn.Editable = False
        oLink = oColumn.ExtendedObject
        oLink.LinkedObject = SAPbouiCOM.BoLinkedObject.lf_Order
The problem I've got though is that if the Sales Order is created with a manually entered Document Number I get the following error when clicking on the linked button.:
"You are not permitted to perform this action [Message 200-30]"
I guess the reason it is happening is that the DocEntry and DocNum are different and the Linked Button is using the DocEntry as reference to which Sales Order needs to be opened when the linked button is pressed.
Is there anyway to stop this from happening and for the Linked Button to function as normal even if the Sales Order has a manually entered document number? So is there a way to allow the Linked Button to link through to a Sales Order using the DocNum not the DocEntry?

Cheers mate. I've just tried setting using the PressLink property of the EditTextColumn object however it's not letting me set the EditTextColumn to the column I have in my matrix. The code I have is:
                                        Dim b As SAPbouiCOM.Column
                                        Dim oEditTC As SAPbouiCOM.EditTextColumn
                                        Try
                                            If pVal.Before_Action = False Then
                                                oForm.Freeze(True)
                                                oEditTC = oMatrix.Columns.Item("DocEntry")
                                                oEditTC.Visible = True
                                                oEditTC.PressLink(pVal.Row)
                                                oEditTC.Visible = False
                                                oForm.Freeze(False)
                                            End If
                                        Catch test As Exception
                                            MsgBox(test.Message)
                                        End Try
The error I am getting is "Specified Cast Is Not Valid". The type of column I am trying to bind to is a "it_LINKED_BUTTON".
