(Adds comments from Waste Management)

BOSTON/NEW YORK, March 26 (Reuters) - Waste Management Inc (WMI.N: Quote, Profile, Research, Stock Buzz) said it spent more than $100 million on a computer system that was supposed to help it save money, but instead turned out to be a "complete failure."

Waste Management spokeswoman Lynn Brown said on Wednesday that her company sued SAP AG (SAPG.DE: Quote, Profile, Research, Stock Buzz) (SAP.N: Quote, Profile, Research, Stock Buzz), the German-based company that sold it the system, seeking all its expenses plus punitive damages.

The No. 1 U.S. trash hauler, which reported $309 million in fourth-quarter net income, has yet to determine whether it will take a charge for its investment in the failed system.

"It depends on what SAP's response is to the lawsuit," Brown said in an email. "We need to assess their response."

SAP spokesman Andy Kendzie declined comment.

The software maker sold Waste Management computer programs that were supposed to be designed to manage tasks unique to U.S. companies that haul waste and handle recycling, with no customization required, the lawsuit said.

Those programs handle tasks including billing, waste logistics, container management and on-board computing, according to a December 2005 press release from SAP America Inc.
