How To Fix FKK_ID_PT_SIGN305 - Prerequisite Document of SAF-T Document & cannot be determined

FKK_ID_PT_SIGN305 - Overview

• Message type: E = Error

• Message class: FKK_ID_PT_SIGN - Digital Signature Portugal FI-CA/IS

• Message number: 305

• Message text: Prerequisite Document of SAF-T Document & cannot be determined

What causes this issue?

An ODN gap is missing in the <ZH>Gaps of Official Document Numbers</>
(DFKK_PT_ODNGAP) table or the specified ODN gap is either inconsistent
or incomplete.

System Response

The system cannot determine the valid prerequisite document that creates
the digital signature for the processed document.

How to fix this error?

Identify if there is a number gap. If yes, you have to declare the lost
number(s) of your given range object in the gap table.
Closing a gap triggers the creation of digital signatures for the
document sequence with missing digital signatures.
Check the entries of the relevant number range object in the gap table
and fix the inconsistency.
Note:
An entry in the gap table is valid if the previous and the following
number are assigned to documents stored in the <ZH>DFKKEXTDOC</> and
<ZH>DFKKEXTDOC2</> tables. Therefore, you must specify sequential
numbers as range and not as separate entries. You must also specify the
complete gap.

Procedure for System Administrators

Gaps in the ODN process are exceptional. If they occur, you must check
and, if required, modify either your customizing or your coding.
