Question about user [GUEST] to update the table [FND_USER]

Hi Exports

Create an user[A] in EBS R12, then use user A login, it asked to reset the password.

Then reset password and login.

Finished as above, I found FND_USER_A insert a new record as below:

"AUDIT_USER_NAME"  "AUDIT_TRANSACTION_TYPE"  "AUDIT_TIMESTAMP"

"GUEST" 　　　　　　　　　"U" 　　　　　　　　　　13-06-28

My question is if in some cases use [GUEST] to update the table [FND_USER] in R12?

Is it specification?

In EBS 11i, the result is as below:

AUDIT_USER_NAME AUDIT_TRANSACTION_TYPE AUDIT_TIMESTAMP 

　　SYSADMIN　          U                 13-06-28
