How to fix this error?

<ZH>If you are authorized to execute digital signatures:</>
RESET N1
Ask your system administrator to maintain the SSF information about user
&V1& (see Customizing for <LS>Basis Components</>, section <LS>System
Administration</> -> <LS>Administration of External Security Systems
</>).
After the SSF information has been changed, call the dialog box for
digital signatures again.
Execute your signature.
<ZH>If another user with the corresponding authorization must execute
the signature:</>
Depending on the application, choose one of the following procedures:
If your user name can be overwritten when the password is entered, the
signatory should execute the signature in your window directly.
If your user name cannot be overwritten:
RESET N2
Where possible, save the data you have entered so far without executing
a signature.
The signatory must then log on to the SAP system under his own user name
and call the function again.
