Trapping errors in WI description

[Dart, Jocelyn]

Nothing fishy at all, Mike.
Any chance the attribute you were testing was not a pure character type - say type N, where initial = all zeroes?
But again - direct test of the value is not the best way to solve your problem.

Hi Jocelyn,
That's pretty much what I thought, but the results are inconsitent. It DOES
contain something greater than 9 and less than A.... sounds like something
starting with a '<' will fit the bill. However checking for it directly will
not work. Checking ... <> '' doesn't work. Checking initial definitely
fails.
 
Admittedly this is academic as I've gone with your approach by checking
whether a related attribute is blank. I did notice something interesting
though:
 
if &Blah& is initial    " ***** DOES NOT WORK
if &Blah& <> ''         " ***** WORKS!
 
I'm no SapScript expert, but there does seem to be something fishy going on....
 
Thanks for your input,
Cheers
Mike
