• Message number: 308

• Message text: Document starts a doc. sequence and must not have a preceeding document

What causes this issue?

The system has identified this document as the first entity of a
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.

• What is the cause and solution for SAP error message FKK_ID_PT_SIGN308 - Document starts a doc. sequence and must not have a preceeding document ?

  The SAP error message FKK_ID_PT_SIGN308 indicates that a document is attempting to start a document sequence but has a preceding document that it should not have. This typically occurs in the context of the SAP Contract Accounts Receivable and Payable (FI-CA) module, where document sequences are used to manage the flow of financial documents.
  Cause:
  
  
  Document Sequence Rules: The error usually arises when the system expects a new document to start a sequence but finds that there is already a preceding document in the sequence. This can happen if:
  
  A document is incorrectly linked to a previous document.
  The document type settings in the configuration do not allow for a new document to start without a preceding document.
  There is a misconfiguration in the document flow or sequence settings.
  
  
  
  Incorrect Document Type: The document type being used may not be set up to allow for the creation of a new document without a preceding document.
  
  
  Data Entry Errors: Manual data entry errors can also lead to this issue, where a user inadvertently tries to create a document that should not have a predecessor.
  
  
  Solution:
  
  
  Check Document Type Configuration:
  
  Go to the configuration settings for document types in the SAP system (Transaction code: OBA7 or similar).
  Ensure that the document type you are using is configured correctly to allow for the creation of new documents without requiring a preceding document.
  
  
  
  Review Document Flow:
  
  Check the document flow for the specific document you are trying to create. Ensure that there are no unintended links to previous documents.
  If necessary, delete or correct any erroneous links to preceding documents.
  
  
  
  Use Correct Document Type:
  
  If you are using the wrong document type, switch to the appropriate one that allows for the creation of a new document without a predecessor.
  
  
  
  Consult Documentation:
  
  Review SAP documentation or help resources related to document sequences in FI-CA to understand the specific requirements and configurations.
  
  
  
  Testing:
  
  After making changes, test the document creation process again to ensure that the error does not reoccur.
  
  
  
  Related Information:
  
  Transaction Codes: Familiarize yourself with relevant transaction codes such as FPL9 (for document processing) and FBL5N (for account display) to help troubleshoot and analyze document sequences.
  SAP Notes: Check for any SAP Notes related to this error message, as they may provide additional insights or patches that address known issues.
  User Roles and Authorizations: Ensure that the user has the necessary roles and authorizations to create documents in the system, as insufficient permissions can sometimes lead to unexpected errors.
  
  If the issue persists after following these steps, it may be beneficial to consult with your SAP support team or a functional consultant who specializes in the FI-CA module for further assistance.
