The fund composition for a specific fund can be seen for various historic dates in the web application (in the derived holdings tab). Is it possible to access this data (for each of the available dates) through the API?
This question has also previously been asked by another user (see https://community.developers.refinitiv.com/questions/42729/mutual-fund-past-portfolio-holdings-via-eikon-api.html). Has there been any developments on this issue?
I'm not aware of anything having changed in this regard in the last month since the answer was provided on the thread you mentioned. However this forum is not the best place to ask such a question. For an authoritative answer to any content questions the best resource is Refinitiv Helpdesk. This forum is dedicated to things specific to the use of Eikon APIs. The moderators here do not have deep expertise in every type of content available through Eikon. From API perspective, if the data can be retrieved into Excel using =TR worksheet function, it can also be retrieved using Eikon Data APIs. I suggest you reach out to Refinitiv Helpdesk and ask if you can retrieve historical derived fund holdings into Excel. Refinitiv Helpdesk can be reached using Contact Us capability in your Eikon application or by calling the Helpdesk number in your country.
