RFC Problem:"I::001 Only available with the RFC library from 4.0C onwards."

Question

Hello,
Ihave a VBA code that calls a BAPI via RFC to checkout a document. The Problem is that I get an error like in the subject. Here is my Code
Private Declare Sub RfcAllowStartProgram Lib "librfc32.dll" (value As Any)
Sub checkout_file()
Dim oDocument As Object
Dim oDocumentFile As Object
Dim oDocumentFiles As Object
Dim oReturn As Object
Dim oBAPICtrl As Object
'Creating BAPI object
Set oBAPICtrl = CreateObject("SAP.BAPI.1")
Set oConnection = oBAPICtrl.Connection
If oConnection.Logon(0, False) = False Then
MsgBox "No access to R/3 System"
Exit Sub 'Programm beenden
End If
RfcAllowStartProgram ByVal 0&
'Creating lokal instance of BO "Draw"
Set oDocument = oBAPICtrl.GetSAPObject("DRAW", "PM2", "A5N00030059989", "D", "000")
If Err.Number <> 0 Then
MsgBox "No local BO 'Draw' created!"
Exit Sub
End If
Set oDocumentFile = oBAPICtrl.DimAs(oDocument, "CheckOutView2", "DocumentFile")
oDocumentFile("WSAPPLICATION") = "DOC"
oDocument.CheckOutView2 OriginalPath:="D:\test\", _
DocumentFile:=oDocumentFile, _
DOCUMENTFILES:=oDocumentFiles, _
DocumentStructure:=oDocumentStructure, Return:=oReturn
MsgBox oDocumentFiles.RowCount
MsgBox oReturn("MESSAGE")
Set oConnection = Nothing
Set oBAPICtrl = Nothing
End Sub
I have the newest librfc32.dll in my System32 folder (Version 7110.0.46.6208). Where is the problem? Can it be a problem on the application server or something?
Thank you,
Thomander

Hi Thomander,
Note 885058 indicates that the problem is resolved with the latest    
RFC and ICU files. The RFC library is contained in the RFCSDK, please 
ensure that you are using the latest SDK, it can be downloaded from the
following location:                                                                               
Support Packages and Patches                                          
    ==> Additional Components                                         
          ==> SAP NW RFC SDK                                          
               ==> SAP NW RFC SDK 7.10                                
                    ==>Your OS                                                                               
ICU libraries can be downloaded from service market place as part of  
sap kernel. There are contained in the complete package sapexe.car    
& in a seperate package UCLIB.sar                                     
-> service.sap.com/patches                                           
-> Entry by application group                                         
-> additional component                                              
-> SAP Kernel [ select the correct versions] & download the file                                                                               
The naming convention of the library files varies depending on the    
operating system, they may be called                                  
"libicuuc.so.26", "libicuuc.sl.26", "libicuuc26.so" or "icuuc26.dll", 
for example. You must therefore adjust the unpacking statements       
accordingly.                                                                               
Unpack the library to the temporary directory & then move it to the   
kernel directory ("/usr/sap/<SID>/SYS/exe/run").                                                                               
Caution: Make sure that the libicu* libraries do not overwrite any    
existing files.                                                                               
Once you are using the latest RFC and ICU files you should be ok.
Maybe the information in the following link could also be useful for this kind of error:
