document sequence. Such a document must not have a preceeding document.

System Response

If during the signature creation for the document a preceeding document
is found by the system, an error is raised. The digital signature
process is aborted.

How to fix this error?

Ensure that the document numbers have been generated consistently by the
system.

Procedure for System Administrators

You must ensure that the events that you have customized for your
business needs are generating consistent official document numbers
and/or SAF-T numbers.
In case you have modified the standard coding for the official document
numbering and/or for the digital signature, ensure that the process does
not cause inconsistencies in the official document number generation.
<ZU>Note</>:
A consistent generation of an official document number or a SAF-T
document number requires that numers are unique for a company code and
for a fiscal year. Sequential numbers must not be cut off and leading
zeros must not be deleted.
For SAF-T documents, the prefix must not be changed in a document
sequence.

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.
