Duke Uni ED IDOC Request Meaning

Hello everyone! Today I received an IDOC request from Duke University through the CSS Profile. Does this mean anything regarding my acceptance?

No. The financial aid just needs some information. They do their analysis at the same time as admissions.

I received a mail to submit IDOC from college board as NYU was requesting them, and NYU specifically states not to submit any IDOC documents unless they request on their website. Does this mean something? @Eeyore123
Also my friend applied with me, but he didn’t receive any mails regarding IDOC from NYU. So what does it say?
