Silly question: Negative object keys...

[Michael Pokraka]

Hi Mark,
The good ol' ZDEADLINE.... albeit a slightly advanced version of the one =
in
the book, we need reverse factory calendar calculations for our deadlines=
.
 
The workarounds are many and varied, but the idea of having numerics but =
no
negatives annoyed me a little out of principle. I understand the SAP
concepts behind its data types (thanks Sheldon, for the detailed low-down=
),
but I can't see the reason for the limitation.
 
Anyway, it was just trivia...
 
Cheers
Mike
