Leo Apotheker had been with SAP for more than 20 years
The chief executive of German software company SAP, Leo Apotheker, has resigned after his contract was not renewed, the company has said.
SAP said the decision not to renew the contract was reached by mutual consent.
The company said it would now return to a split leadership, with executive board members Bill McDermott and Jim Hagemann Snabe sharing the helm.
Mr Apotheker, who had been in sole charge for seven months, had been with the company for more than 20 years.
He was named co-chief executive with Henning Kagermann in April 2008 and took over the sole responsibility for leading the company after Mr Kagermann's retirement in July 2009.
During Mr Apotheker's leadership SAP announced 3,000 job cuts, which was a first in the company's history.
The resignation caused SAP's shares to drop by more than 1% in early trading on Monday.
