How to check if ISIN exists in Datastream database?

feldman.lee

Hi can I check if there exists a function that checks whether an ISIN is not available in Datastream API? Currently I am just requesting for these ISINs and checking if the $$ER: E100,INVALID CODE OR EXPRESSION ENTERED is given in the Value column. Thanks.

df = ds.get_data(

tickers='US606822CR31',

fields=['CMPB', 'CMPA'],

start='2024-06-15',

kind=1

)

Thank you for reaching out to us.

You can search it on the Datastream Navigator.

However, it is better to contact the Datastream support team directly via MyAccount to confirm it.
