Hi,
This is for installing Diagonisitic Agent...
Now a days, by default, it is being installed by default along with the installation / Migrations.
Please provide the password for sapadm so that you can login and later start/stop the diagonisitic agent as per your it is required.
It is not possible to skip this option in today's sapinst or swpm.
So please proceed with the password and continue.
Regarding the label.ASC, i have provided the same label.asc to you as suggested by SAP too.
Thanks and Regards,
Vimal
