Sorry, I have forgotten the most important:
to find the right formula to complete:

Option Explicit

Sub AddToFormula()
Dim xR As Range, xF

For Each xR In ActiveSheet.UsedRange
xF = UCase(xR.Formula)
If Not IsNull(xF) Then
If Not (Len(xF) = 0) Then
If InStr(xF, "45*VLOOKUP($") 0 Then
If InStr(xF, "*CODE!$C$47") = 0 Then
xR.Formula = xR.Formula & "*Code!$C$47"
End If
End If
End If
End If
Next xR

End Sub

Hello,

A beginning of solution using VBA:
The active sheet must be the sheet where the formula to be changed are.

'''''''''''''''''''''''''''''''''''''''''''''''''' '''''''''''''''''''''''''''''
Option Explicit

Sub AddToFormula()
Dim xR As Range, xF

For Each xR In ActiveSheet.UsedRange
xF = UCase(xR.Formula)
If Not IsNull(xF) Then
If Not (Len(xF) = 0) Then
End If
End If
Next xR

End Sub
'''''''''''''''''''''''''''''''''''''''''''''''''' '''''''''''''''''''''''''''''

I have many formulas in a sheet like :

=ROUND('Revenue'!D$45*VLOOKUP($C116,ItemSplit!$A$1 :$B$50,2,FALSE),0)

If the the formula do not contain *Code!$C$47 (multiply by) at the end
of the formula i want to add it to all the formula in the sheet.

Can it be done using VBA or by find, replace function

Thanks
