E11 Duplicated unique value

Constant
E_UNIQUE
Specification
§6
Lenient mode
Recorded and the document is built anyway

A unique field repeats a value already seen in another valid record. A rejected line does not reserve its value.

How to see it

In the playground, “Editor & validator” tab, the “Inject 3 errors” button triggers E04, E05, E08 and E09 on the loaded example. From the command line, mini diagnose archivo.mini prints a JSON report with every error and the lines to regenerate.
