DVD 13.0 (approx. August 2019) will change the processing method for fixed-write indicators in DATEV Accounting.
Previously, data was imported and fixed without a fixed-write indicator. The user could, however, cancel the fixing of the data by means of a setting in the user and rights management.
As of DVD 13.0, it will no longer be possible to remove the fixing if the fixing indicator is missing.
Recommendation: Always transfer the fixed-write indicator in DATEV interfaces. Only then can the user cancel the fixing if necessary.
