If your institution has sent the documents directly then it should be faster than other cases as WES won't send them back for secondary verification.
I think they are evaluating your PGDM diploma, but they have not given any completion date. IMO it will take some time as they update status with a completion date and then they send you the copy of the evaluation report in the mail(which takes 8-12 business days for India).
In your case, I think ECA# will be same as you are adding credentials to your existing report (Just confirm with them once).
Oh ok.. yes they are evaluating my PGDM diploma. and my status hasn't changed yet... lets see by this month end.. as feb 19th is my last date for ITA...
