Can you share the code and explicit error messages?
Which function module are you using (RFC_READ_TABLE)?
I have a Visual Studio application that uses the same SAP.Functions object and RFC_READ_TABLE, and it is still working without error.
A few lines from that application:
'Get the table of field names for the function module
objFields = objRFC_READ_TABLE.Tables("FIELDS")
'then add the list of field names in a loop with lngRow as a counter ...
objFields.AppendRow()
objFields(lngRow + 1, "FIELDNAME") = lstFields(lngRow).ToString
