Change Username in Oracle EBS


It's a kind of rare requirement to change the username in EBS.  This can be accomplished by using 2 methods.
  1. Either by using Front end.
  2. Or by using the Oracle Provided Package APPS.FND_USER_PKG.

It is not recommended to update any FND_USER column by using direct UPDATE SQL.  Oracle uses this column to maintain the foreign key relationship with few WF tables(For Ex: WF_LOCAL_USER_ROLES)

  1. By using Front end.
           Login to ERP -->  System Administrator  --> Security --> User --> Define.  It launches Java form similar to the below screenshot.

            


Press F11, Enter the old username and search by using Ctrl + F11.  Change the User Name field to New value.  Don't forget to save. 


   
  2. By using FND_USER_PKG

begin
     fnd_user_pkg.change_user_name(x_old_user_name => 'oldusername', x_new_user_name => 'new_user_name');
     commit;
end;
/


This is really helpful when you are integrating EBS with OID or IDAM.
