I’m interested in accessing TR.UltimateParentID for a specific day with the Eikon API. I want to answer questions like “Who was Github’s Ultimate Parent“ on Dec 10th 2017?” I would like to do something similar with TR.RelatedOrgID. However, these fields don’t seem to support any date parameters. Are there any solutions to this through the Eikon API or other Refinitiv services?
I don't believe point in time organizational structures are available through Eikon or any other Refinitiv products. However, for an authoritative answer I would suggest directing your question to Refinitiv Helpdesk, which can be reached using Contact Us capability in your Eikon application or by visiting MyRefinitiv. The moderators on this forum have expertise in Refinitiv APIs, but don't necessarily have deep expertise in every type of content available through Refinitiv products. The latter is available through Refinitiv Helpdesk.
