Dynamic condition in UDO Matrix's Column

Question

Hi all,
I have a user form with a matrix. The matrix's first column has a CFL linked to another UDO MasterData Code (lets call it UDOCode).
And on this matrix, the same UDOCode cannot be chosen more then once.
So, I've been trying to code a dynamic CFL that filters the UDOCode's already chosen in the Column.
Based on this thread I've achived this code:
Select Case pVal.ItemUID
                    Case "mtx_ACORDO" '// The Matrix
                        oConds = New SAPbouiCOM.Conditions
                        With oForm.DataSources.DBDataSources.Item("@ADAT_ACORDOS1") '// The Matrix's DBDataSource
                            If .Size = 1 Then
                                oCond = oConds.Add
                                oCond.Alias = "Code"
                                oCond.Operation = BoConditionOperation.co_NOT_NULL
                            Else
                                For i As Integer = 0 To .Size - 1
                                    oCond = oConds.Add()
                                    oCond.BracketOpenNum = 1
                                    oCond.Alias = "Code"
                                    oCond.Operation = BoConditionOperation.co_NOT_EQUAL
                                    oCond.CondVal = .GetValue("U_EspPrcCd", i)
                                    oCond.BracketCloseNum = 1
                                    If i > 0 And i < .Size - 1 Then
                                        oCond.Relationship = BoConditionRelationship.cr_OR
                                    End If
                                Next
                            End If
                        End With
                End Select
If Not oConds Is Nothing Then oCFL.SetConditions(oConds)
In the matrix's first row I have no problem. All the values are there. But on the second row, no values are display in the DataTable.
If I change the conditions from .Size -1 to .Size - 2, I get the correct values on the first and second rows, but on the third, again, no values are being display in the DataTable...
Can anyone help me?
Regads,

Hi, Erwine Sukardy
Maybe it will be helpful if you have a specific task.
All of items on a Form have it's own DBDataSources.
For example, to get a table name and field name, that are Datasources to the ItemCode field in a Matrix in a  Purchase Order document, you can use this code:
SAPbouiCOM.Matrix        tblSNs;
SAPbouiCOM.Column      oColumnItems;           
tblSNs = (SAPbouiCOM.Matrix)oPurDNForm.Items.Item("38").Specific;
oColumnItems = (SAPbouiCOM.Column)tblSNs.Columns.Item("1");
string tableName = oColumnItems.DataBind.TableName;
string fieldName = oColumnItems.DataBind.Alias;
HTH!
