How to fix this error?

Contact your system administration.

Procedure for System Administrators

Import the key with the name "&V1&" into the secure storage in the file
system. You can use the key management function in transaction SECSTORE
to do this.
Use the backup copy of the key that you were prompted to create when
generating the key as the source for restoring it.
Examples of reasons why the key for the entry "&v2&" is not currently in
the secure storage in the file system:
The database tables of the secure storage come from a different physical
or logical system (system copy).
The secure storage in the file system was manually deleted.
The profile parameters that configure the secure storage in the file
system (rsec/ssfs_datapath; rsec/ssfs_keypath) do not have the same
values on all instances of the system, meaning that multiple versions of
the secure storage in the file system are seen by the instances.
