In **E****xcel** when asking for the starmine rank I don't need to supply any additional parameters.

In **Codebook **it ask me to supply fields or functions I don't understand in the first place why I need to supply additional information and second it is not clear to me what I need to supply then.

Please help me solve this!

See the comparison Python and Excel below:

**Excel:**

=TR("NVDA.O","TR.IVPriceToIntrinsicValueGlobalRank","CH=Fd RH=IN",B2)

see below also that the expected result is returned

__CODEBOOK (Eikon):__

import refinitiv.data as rd rd.open_session() print(rd.__version__) print("-----------") fields = ["TR.IVPriceTolntrinsicValueGlobalRank"] EikonData = rd.eikon.get_data(instruments= "AAPL.O", fields= fields) print(EikonData)

I get the following confusing error message:

'The formula must contain at least one field or function.'
