When I run this code in Python:
...
index = '.STOXX'
DateR='2018-12-31'
df,err = ek.get_data('{}{}({})'.format('0#', index, DateR), fields=['TR.TRESGCScore'],
parameters={'SDate': '{}'.format(DateR), 'Period': 'FY0'})
...
Python returns N/A for some instruments like BOUY.PA. However the DIB of the same date and instrument reports 64.44.
How can I obtain the right historical ESGC Score in my Python request for all instruments into an index at a specific date?
For ESG scores I strongly recommend to not use the SDate parameter, and instead specify the absolute financial period in the request. E.g. to retrieve the scores for 2017 use
ek.get_data('0#.STOXX(2018-12-31)', ['TR.TRESGCScore'],
{'Period': 'FY2017'})
Note that in the above expression the significance of the 2018-12-31 date is only that the index constituents are returned as of that date.

Hi @patrick.sentis,
There doesn't appear to be any ESG data for the .STOXX price index. I would suggest you contact the helpdesk when inquirying about data availability.
Regarding BOUY.PA, I am able to retrieve historical scores. You didn't include a code example to confirm. This is what I did:
df, err = ek.get_data(['BOUY.PA'],["TR.TRESGScore(SDate=2018-12-31,Period=FY0)"]) df
The above field was generated by the DIB.
@nick.zincone.1 and @Alex Putkov: Thank you very much for your replies. Indeed, it works and I have found a similar solution before my query. However the backward updating of rate significantly deprecates any historical study based on the older rates. It's a pity to not have a comprehensive and consistant historical database on ESG data.
