DSXchange

You can always use the "short" (sometimes called "8+3") names in a pathname to avoid using special characters.

Of course, and the "short" version is the first six characters followed by "~1" for the first unique occurance and incrementing from there. So more than likely "format~1" for "formation DS". Plus the extension, if any.

... except where this convention might lead to duplicates, when you start to get ~2, ~3 and so on at the end of the basename.

As I noted.

I know its not a solution and I would be happy to find one, but meanwhile, it's a way to keep moving on my course.

Can anyone tell me what's going wrong, knowing now that suppressing the space, the scheduled job runs OK?

Your official support provider, who would first determine if it was indeed a bug in the product, I would imagine.
