Orthographic typically isn't known early in an SA project. Maybe adjust to use the Ethnologue code in:
Information --> Source --> Ethnologue ID field.
If not defined, fall back to "und".
A future issue could add a line in the Lift Export dialog to mirror the Ethnologue ID field and maybe warn if undefined.

I note SA historically used the Orthographic field to build the lexical unit https://github.com/sillsdev/SpeechAnalyzer/blob/d1191aa6e158f1825994a804163fd77df6ae8da5/Src/SA/Sa_Doc.cpp#L7491
