Hi, Sergey
Thanks for clarifying
Sorry, my experience with Arelle is only to use it to load data from the SEC into Postgres. I don't have any experience loading it back into Arelle (I assume you want to do this so you look at it through the Arelle GUI?)
There was a thread on this board back in March called "New Arelle User" that discussed this subject, but unfortunately didn't have an answer to the question.
Good luck with your task.
Best from Mike
