SAP has been slapped with a lawsuit by California's state controller over a payroll software implementation the office says cost taxpayers a vast sum of money, but has never worked correctly. "After three years, and paying SAP approximately $50 million to integrate its own software into a new payroll and benefits system for the state of California, all the [state controller's office] has to show for its investment is a system that could not get the payroll right even once over an eight-month period for a pilot group of only 1,500 employees," the lawsuit states.
