Log on Problem while connecting to Sap form lotus!

Hi,

There is no problem while i am doing connection from my mail address book (in louts notes) to sap.

but when i am doing connection from mail database (in lotus notes) to sap by using the same parameter as in earlier case then it showing the Errro as →

log on Erro key:

STATUS:

MESSAGE:

INTSTAT::

The code is as follows:—

Set rfc_srv = New RFCServer

rfc_srv.User = sapflds(0)

rfc_srv.password = sapflds(1)

rfc_srv.Client = sapflds(6)

rfc_srv.Destination =sapflds(4)

rfc_srv.System = sapflds(5)

rfc_srv.Language = sapflds(7)

rfc_srv.HostName =sapflds(3)

rfc_srv.EnableSapGui = 0

If rfc_srv.Logon() <> True Then

Call sap_msg ("Logon error " + rfc_srv.Message)

Goto ERR_XIT

Else

'Call sap_msg ("Logon OK " + rfc_srv.Message)

End If

The error is showing because rfc_srv.Logon() <> True.

so what could be the problem as same thing is working well in addressbook???

Thanks in Advance !!
