Hello! I would like to download Issuer and Issue (e.g. Bond) ratings controlling for different sources (credit rating agencies). I am currently using the following formula:
df, err = ek.get_data(instruments=['BondRIC1', 'BondRIC2'],fields=['TR.IssuerRating(IssuerRatingSrc=MBC)','TR.IssuerRating(IssuerRatingSrc=MBF)'])
Whare BondRIC1 and BondRIC2 are identifiers for bonds and MBC and MBF are different codes for rating types at Moody's. How can I configure this formula to also download Issue not Issuer ratings? Many thanks!
