2.3.2 Procedure for electronic signatures
Program parts: Database / Method
Methods and determinations exhibit one of the following three states in
relation to signatures (see flow diagram):
￭ Not signed
Methods and determinations which are not signed can be deleted and
changed, a new version being created at each change.
￭ Signed (1)
When signing methods and determinations at Level 1, no new versions
are generated. If methods and determinations signed at Level 1 are
changed, a new version is generated, which no longer contains any sig-
natures. Methods and determinations signed at Level 1 can be deleted.
￭ Signed (2)
When signing methods and determinations at Level 2, no new versions
are generated. Methods and determinations signed at Level 2 can neither
be changed nor deleted. However, it is possible to delete the signatures
(2), whereby the signatures (1) are retained.
