The following rules apply:
• Signature levels
Methods and determinations can be signed at two levels (Signature Level 1
and Signature Level 2) by entering the user name and password.
• Multiple signing
Methods and determinations can be signed several times at each level. All
the signatures are saved and documented in the Audit Trail.
• Sign at Level 1
If Level 2 has been signed then no more signatures are possible at Level 1.
• Sign at Level 2
Level 2 can only be signed when signatures already exist at Level 1.
• Different users
The same user can only sign at either Level 1 or Level 2.
• Reason and note
Each signature must be accompanied by a reason selected from prede-

• Saved data
The signature date, user name, full name, reason and note are saved for
each signature.
• Deleting Level 1 signatures
Signatures at Level 1 are automatically deleted when a new version is gen-

• Deleting Level 2 signatures
Signatures at Level 2 can only be deleted by users who have the appropri-

• Signing methods
Methods can always only be signed individually.
• Signature options
The options for electronic signatures are set on the tab Signatures in the
dialog window Security settings .
