It’s been a while since German business software maker SAP has stated exactly how much of a market share it has.  And no matter how much journalists prod and badger SAP CEO Leo Apotheker he will not divulge that figure. Even when analysts say they believe that SAP’s main rival Oracle has been taking market share from the German company, Apotheker will not be moved to shed some light on the issue.  In several TV interviews on Wednesday, the day SAP presented its second-quarter results, and in a call with analysts, Apotheker not only declined to provide even a range, in fact he could not bring himself to call his company’s fiercest rival by name. “We have about twice as much market share as Number 2,” he said.  In the Harry Potter series the hero is the only one who calls his nemesis by name – Lord Voldemort - instead of ”he who must not be named”.  C’mon Leo, if Harry Potter can do it, so can you.
