Schema error
afdDefinitionName incorrect (a fixed value since the final Release 2027)
Symptom
Schema error 'must be equal to constant' on afdDefinitionName; the WTP Data Lab validator names the expected value. Typical of a message built on the July 2026 pre-release: it states the right version 001.05 and still fails.
Cause
Since the final Release 2027 (12 October 2026) afdDefinitionName is a fixed value in every message: the file name of the schema with 001.00, for example VBPUO-001.00-Bericht_2._Cashflow_(0001b). The version is only in afdDefinitionVersion (manual section 7.5.1.1, issue #140). In the pre-release the name was free; SIVI's own chunk samples carried Pensioenprojectie_0001c. In the pre-release the feedback message had the fixed name VBPUO_Feedback_Message-001.02-VBPUO_Feedback_Message; it now has VBPUO_Feedback_Message-001.00-VBPUO_Feedback_Message. In Release 2026 the name is free text, except in the feedback message.
Fix
Copy the fixed name of the message; the code list page afdDefinitionName shows all eleven. Do not derive the name from the version: that sits separately in afdDefinitionVersion.
