I wrote a mass change popup on an ALV grid. The users can now freely select rows and do a mass change, but when they want to reverse, the IS INITIAL and STRLEN() doesn't recognize spaces. Fair enough, but I'm looking for a workaround? They'd like to enter a single space that will delete the content of a mass selection. I don't want them to enter something like "delete" or "DEL", it must be a single space.
Any ideas? Thank you and best regards, Adrian
