Invalid Form error

Question

Dear Experts,
I have created one matrix and one button in Purchase Order form. when i click on that button one form(frmopr) will be loaded. that form contains one matrix with data and one button.
now i select one or more line in the matrix and click the button. the selected line value should be displayed in user matrix in PO form. i am using following code
If pVal.FormUID = "frmopr" Then
                If pVal.ItemUID = "chs" And pVal.EventType = SAPbouiCOM.BoEventTypes.et_ITEM_PRESSED And pVal.Before_Action = True Then
                    oForm = SBO_Application.Forms.Item("frmopr")
                    oMatrix = oForm.Items.Item("matrix").Specific
                    j = 1
                    For i = 1 To oMatrix.RowCount
                        If oMatrix.IsRowSelected(i) = True Then
                            oEdit = oMatrix.Columns.Item("series").Cells.Item(i).Specific
                            rema(j) = oEdit.Value
                            oEdit = oMatrix.Columns.Item("docNo").Cells.Item(i).Specific
                            dn(j) = oEdit.Value
                            'SBO_Application.MessageBox(rema(j))
                            j = j + 1
                        End If
                    Next
                    oForm.Close()
                    POForm = SBO_Application.Forms.Item("142") '<- error Line <<
                    oMatrix = POForm.Items.Item("38").Specific
                    For k = 1 To j - 1
                        POForm.DataSources.DataTables.Add("MyDataTable")
                        POForm.DataSources.DataTables.Item("MyDataTable").ExecuteQuery("Select U_itemcode, U_Qty from [@PRR1] where U_series=" & rema(k) & "and U_DocNo=" & dn(k))
                        POForm.Items.Item("Umatrix").Specific.Columns.item("1").DataBind.Bind("MyDataTable", "U_itmcode")
                        POForm.Items.Item("Umatrix").Specific.Columns.item("11").DataBind.Bind("MyDataTable", "U_itmQty")
End If
End If
its throwing error message " Invalid Form" in above mentioned line
Please Give a Solution

Hi Mathi,
System forms do not have a static formuid.142 is the form.typeex of Purchase Order form.Formuid changes on every opening of the form like F_42 and so on.So its better to pass this formuid when you are referring to the form like
    Select Case pVal.FormTypeEx
Case "142"
your code for itemevent
End Select
And in your user form you need to get this formuid
so that your code looks like
poform=Sbo_Application.Forms.Item(formid)
where this formid is passsed as a parameter.
