Business Function Build Error: Undeclared Identifier

Hello, list! Last time I built a full client package, it completed without errors. This time (several months later), I'm getting errors galore.

Most of the errors have this in common: error C2065: 'DSD0000176' : undeclared identifier

What's missing?

Fixed Business Function Build Error: Undeclared Identifier

Because of the nature of the error, I suspected a header file was missing or corrupt.

Found DV7334\source\N1200090.c (a JDE standard object) and scanned through the code; one include file, B0000176.h, jumped out at me because its name is so closely related to the 'DSD0000176 ' undeclared identifier. Found DV7334\include\B0000176.h -- 0 KB modified 6/14/05 at 9:22 AM!

Compared the same file in JD7334\include and PD7333\include (on a production workstation); they are same, both 8 KB with timestamp 6/30/1998 3:33 PM. Copied one of them over to DV7334\include and rebuilt the package. 0 errors. Zero, zilch, nada.

So...Now that it's fixed, can anybody hazard a guess as to how it could have happened??
