CRTDUPOBJ - WRKOBJPDM vs WRKOBJ

We are on IBM I V7R3.
I am confused about the following:

I run command WRKOBJPDM LIB(library) Obj(name*) to get a list of name*
objects. I execute option 3 with prompt to run CRTDUPOBJ command on a
physical file. The command pops up with parm DATA(*YES). So when I copy
the file, the data comes with it.

I run command WRKOBJ lib/name* to get the same list of files. I execute an
option 3 with prompt to run CRTDUPOBJ command. The command pops up with
parm DATA(*NO). So when I copy the file, the data DOES NOT come with it.

The default on the CRTDUPOBJ command is DATA(*NO).

I cannot figure out where the CRTDUPOBJ from the WRKOBJPDM display is
getting the DATA(*YES).
Can some one point me to where this would override behavior would be
defined?

There are 4 versions of CRTDUPOBJ on the system - but the only one I would
be accessing is in QSYS.

Object Type Library
CRTDUPOBJ *CMD QSYS
CRTDUPOBJ *CMD QSYSV6R1M0
CRTDUPOBJ *CMD QSYSV7R1M0
CRTDUPOBJ *CMD QSYS38

Incidentally, this discrepancy led me to make an EMPTY backup file when I
thought I was making a complete data backup.
Mea culpa for not being diligent.
