The endpoint AccountName consists of the country code and systemusername value. For eg: if country code is A and systemusername is mayank then accountname will be Amayank.
Note: If users.Country eq India in Saviynt doesn't mean that the country code will be I for the application. There are close to 15 country codes with unique specific characters.
@mayankshah, if my understanding is right, the query is that you're trying to dissect the account name and correlate it with the user whose system username is part of that account. Please correct me if I'm wrong.
Are the country codes all a single alphabet or is it different no. of letters for different countries.
