U_CandisLink_AP is the technical field name of a user-defined SAP B1 field (UDF) at document level that the DMS system CANDIS populates with the archive link of the respective document during automated import of incoming invoices. From VFS v04.2026, the DATEV export reads this field as a fallback source for the document link.
Context
The field belongs to the two-stage fallback logic of the VFS-DATEV export: If the primary DMS link field at the journal posting level is empty, the export defaults to U_CandisLink_AP back. This eliminates the need for CANDIS users to manually maintain the journal posting field — the document link for the tax firm functions automatically as long as CANDIS correctly populates the field.

Demarcation
U_CandisLink_AP This is a CANDIS-specific field, not a VFS in-house development. The VFS reads it but does not write to it. The field only exists in tenants where CANDIS is installed and configured.
