Just a guess, but is Library1 and/or Library2 in your library list?
If so try removing them from your library list, and adding libary3
to your library list.  Then try the sequence of commands.  See if that
does it.

Hi all

I'm trying to get round a limitation in CRTDUPOBJ as hopefully this
scenario illustrates:

Library1 has physical files A and B, and logical files X and Y.
Library2 has physical file C and logical Z.
File X is a join logical over both physicals A and B.
File Y is a logical over physical B.
File Z is a join logical over both physicals A and C.

I want to create a test environment (in Library3) with all these files.

1) CRTDUPOBJ OBJ(A) FROMLIB(LIBRARY1) OBJTYPE(*FILE) TOLIB(LIBRARY3)
2) CRTDUPOBJ OBJ(B) FROMLIB(LIBRARY1) OBJTYPE(*FILE) TOLIB(LIBRARY3)
3) CRTDUPOBJ OBJ(C) FROMLIB(LIBRARY2) OBJTYPE(*FILE) TOLIB(LIBRARY3)
4) CRTDUPOBJ OBJ(X) FROMLIB(LIBRARY1) OBJTYPE(*FILE) TOLIB(LIBRARY3)
5) CRTDUPOBJ OBJ(Y) FROMLIB(LIBRARY1) OBJTYPE(*FILE) TOLIB(LIBRARY3)
6) CRTDUPOBJ OBJ(Z) FROMLIB(LIBRARY2) OBJTYPE(*FILE) TOLIB(LIBRARY3)

At V4R3M0 1) to 5) completed and 6) failed. At V4R4M0 6) now completes
but logical Library3/Z points to Library1/A, not Library3/A. This is in
keeping with the documentation, but I want Library3/Z to point to A & C
in Library 3 (not much of a test environment otherwise ;-) ).

I've tried deleting and recreating (ADDLFM) the logical file member to
point to the correct file, but it fails. A save/restore doesn't do the
trick either. The only option I know that works is to recreate from the
source. On our development box that isn't a problem, as we have the code
for virtually all our software but it's a bit cumbersome. In a setting
where the source member isn't available I can only think of creating one
(from the the file APIs) and compiling against that. That seems even more
contrived.

Can anyone point out a solution I've missed out (other than a better DB
structure - I'm not able to do anything about that as yet :-( ). I'm
after a generic solution I can include in my DBG/400 software for other
people in the same situation - I guess I'll go with the create source
method if I can't avoid it.

Regards, Martin
