WALLDORF (dpa-AFX) - Europe's largest software manufacturer SAP and its designated Supervisory Board Chairman Punit Renjen are surprisingly going their separate ways. The US-American, who was intended to succeed co-founder Hasso Plattner, will resign from the Supervisory Board at the Annual General Meeting in May, the DAX heavyweight announced on Sunday evening in Walldorf. The reason for this was the different ideas about the role of the future Chairman of the Supervisory Board. SAP presented a replacement for Renjen in the form of former Nokia manager Pekka Ala-Pietilä. The Finn is to be proposed for election to the Supervisory Board and is also envisaged as Chairman of the Board./men
