Hello Samid
You have 2 options:
1. Login with another user having Administrator privileges and reset the password of your 'Administrator' user.
2. If you do not have any other user with Administrator privileges, then activate SAP Superuser (SAP*) and reset the password of your 'Administrator user. To activate, you need to:
a. Login to configtool.
b. Navigate to Global Server Configuration -> Server -> Services -> com.sap.security.core.ume service and set properties:
- ume.superadmin.activated = true
- ume.superadmin.password = <set your desired password>
Save the changes, and restart J2EE Engine.
c. Login with SAP* user account in /nwa. Reset password of your 'Administrator' user.
d. Deactivate SAP* user in configtool.
e. Restart J2EE Engine.
f. Login using your 'Administrator' user.
I hope this helps you. If yes, please assign points.
Thanks.
