There are several posts in One Community on how attribute dimensions that are based on the entity dimension work.
Here is one: Attributes and Aggregation - November 2022 | OneStream Community
And another: JIRA Ticket: PF-19348
If you do a search in One Community for 'Attribute Entity' you will see many other posts that I think will explain how attributes based on the entity dimension work, considerations, etc.
Thanks for you answer. Prior to writing this post, I've watched the whole video you sent as well as read some articles.
Maybe I'm mistaken, but I cannot see anywhere the explanation for why 'api.data.calculate()' does not include attributes members even when hardcoded in source formulas whereas data buffers do take them into account (if a property is activated).
For anybody searching for a way to include attributes members in 'Custom Translations', you need to use buffers. Beware of account types & flow properties ! If you use data buffers, you have to isolate all non-translated accounts such 'Flow, Balance & Non-Financial'.
