Merci pour ta réponse . Petit bout de macro qui résume :
Sub sup()
Sheets("T").Select
Application.ScreenUpdating = False
Dim i As Long
For i = Range("A65536").End(xlUp).Row To 2 Step -1
If Cells(i, 16).Value > 899999 Or _
Cells(i, 2).Value = "Z1" Or _
Cells(i, 2).Value = "D8" Then _
Rows(i).Delete
Next i
Application.ScreenUpdating = True
Sheets("M").Select
Application.ScreenUpdating = False
For i = Range("A65536").End(xlUp).Row To 2 Step -1
If Cells(i, 16).Value > 899999 Or _
Cells(i, 2).Value = "D8" Then _
Rows(i).Delete
Next i
Application.ScreenUpdating = True
End Sub
