J'étais pas réveillé ce matin, c'est bon j'ai modifié le code cela fonctionne. Le voici :
Sub Div_1()
Dim O As Worksheet
Dim TV As Variant, x As Variant
Dim TEST As Boolean
Set O = Worksheets("DivALL")
TV = O.Range("A1").CurrentRegion
For I = 2 To UBound(TV, 1)
TEST = False
For J = 2 To UBound(TV, 1)
For K = 2 To 4
If Right(TV(I, 1), 6) = Right(TV(J, K), 6) Then TEST = True: GoTo suite
Next K
Next J
If TEST = False Then O.Cells(Application.Rows.Count, "A").End(xlUp).Offset(1, 0).Value = TV(I, 1)
suite:
Next I
MsgBox "Données traitées !"
End Sub
