How to fix 'Undefined function 'xxx' in expression' (Excel Function in SQL Query) - sql

Question

I am trying to call an Excel function to a SQL query, but I keep getting the same error : "Undefined function xxx in expression".
I'm working with Excel only due to customer choices.
I've checked if references were missing,
My function is in a valid Module wiht Option Explicit, and it is declared as Public.
And i made sure I had a return value.
Thank you for your time
There is my function
Public Function CalculRamasseCarriste(ByVal lng_QTE As Integer, ByVal str_CodeArticle As String, ByVal lng_QTEmax As Integer) As Boolean
Static lng_cumulQTE As Integer
Static str_Text As String
Static bln_Prendre As Boolean
If str_Text = "" Then
str_Text = str_CodeArticle
ElseIf str_Text <> "" Then
If str_Text <> str_CodeArticle Then
str_Text = str_CodeArticle
lng_cumulQTE = 0
End If
End If
lng_cumulQTE = lng_cumulQTE + lng_QTE
If lng_cumulQTE < lng_QTEmax Then
CalculRamasseCarriste = True
bln_Prendre = True
ElseIf lng_cumulQTE >= lng_QTEmax And bln_Prendre = True Then
CalculRamasseCarriste = True
bln_Prendre = False
Else
CalculRamasseCarriste = False
End If
End Function
And there is my query :
Return_Qry_Ramasse = "SELECT T1.[Adresse], T1.[N° Support], T1.[Code_Article], T1.[Libellé_article] " & _
" FROM [V_Stock$] as T1 " & _
" LEFT JOIN [Cmd$] as T2 on T1.[Code_Article] = T2.[Code_Article] " & _
" WHERE CalculRamasseCarriste(T1.[Nb Box-Colis / Pal], T1.[Code_Article], T2.[UVC_cmd])= True " & _
" ORDER BY [Code_Article], [Adresse], [N° Support]"
