￭ Signing at level 2
Level 2 can not be signed unless there are already signatures on level
1.
￭ Different users
The same user may not sign on both level 1 and level 2.
￭ Reason and comment
Each signature must be accompanied by a reason selected from prede-
fined default reasons. An additional comment can also be entered.
￭ Saved data
Signature date, user name, full name, reason and comments are saved
for each signature.
￭ Deleting signatures 1
Signatures at level 1 are automatically deleted again when a new ver-
sion is created.
￭ Deleting signatures 2
Signatures at level 2 can only be deleted by users who have the respec-
tive permission.
￭ Signature options
The options for electronic signatures are set in the Signatures tab in
the Security settings dialog window.
2.3.2 Procedure for electronic signatures
Program part: Database
Determinations exhibit one of the following three statuses with respect to
signatures (see flow diagram):
￭ Not signed
Determinations that are not signed can be deleted and changed, with
a new version being created each time there is a change.
￭ Signed (1)
No new versions are generated when determinations are signed at
level 1. If determinations signed at level 1 are changed, then a new
version will be generated that no longer contains any signatures.
Determinations signed at level 1 can be deleted.
￭ Signed (2)
No new versions are generated when determinations are signed at
level 2. Determinations signed at level 2 can neither be changed nor
deleted. It is, however, possible to delete the signatures (2), although
the signatures (1) will be retained.
