OAAT AG Withdraws the Announced Update of TarDoc/LKAAT

Tuesday, 7 July 2026

OAAT AG, the copyright holder of the TarDoc and LKAAT/ACF tariffs, has withdrawn the technical update announced in Newsletter 34, dated 16 June 2026, which had been scheduled to take effect on 14 July 2026.

As a result, no new versions of tardocValidator100 or acfValidator100 will be released for 14 July 2026. At the time of writing, no information is available regarding whether, or when, these withdrawn updates will be released.

 

Upcoming Updates to the Sumex1 System

Two updates to the Sumex1 system will be released in the coming days. These updates are directly related to the withdrawal of the OAAT update or were postponed as a consequence of it.

 

1. Update of tardocValidator100
This update includes only an updated version of the RESTful server tardocValidatorServer100.exe. All other components, including the TarDoc database, remain unchanged.
 
This update is required only for software vendors and system integrators that use the REST server in production. For all other installations, applying this update is optional.

 

2. Update of generalInvoiceRequest500
The update of generalInvoiceRequest500 consolidates several minor corrections that have been implemented over time but were not previously released due to their negligible technical and operational impact.
 
The update contains only cumulative, non-business-critical changes. Installation of this update is also optional.
