Importing Automatically Generated Profiles after Installation 
Use
The R/3 instance profiles are automatically generated or updated at operating system level when you first install an R/3 System, upgrade to a new R/3 Release or add a new application server. Unfortunately, the installation program cannot save these profiles straight to the database. Therefore you must import the R/3 instance profiles file before they can be edited using the profile maintenance tool.
Procedure
There are two ways to import profiles using the profile maintenance tool:
To import R/3 profiles from all active application servers (mass import):
The default profile and all start and instance profiles used by the SAP instances are then imported. The system checks the profiles and displays a log. The names of the profiles in the database are taken from the corresponding file names on the operating system.

If you import the instance profile /usr/sap/C11/SYS/profile/C11_D53, then the profile in the database will be called C11_D53.
To import individual profiles:

This function should be used if a new application server has been installed, or a profile was modified at the operating system level. You must first create a new profile using the profile maintenance function.
Profile type and status now appear on the screen for your information.

The imported profile is then checked for any errors. You can now edit and/or import the profile into the database. Once the import process is complete, you can decide whether you want to activate the profile.
