I saw that when using the function ek.get_symbology, RICs, ISINs can be converted to PermID, however, it seems impossible to convert directly from permid to RICs
permid=['4295857664'] convertrics3=ek.get_symbology(permid, from_symbol_type='OAPermID', to_symbol_type=['RIC','ISIN']) print(convertrics3)
(The description for the error: 2020-11-29 22:04:19,875 P [MainThread 13392] Can not process metadata for request: SymbologySearch.from - value doesn't fall in valid range: [RIC ISIN CUSIP SEDOL ticker lipperID IMO]
Is there any way to convert PermID to RICs, by other functions/instructions?
Can I use the permID instead of RICs to take historical time series data?
