But SAP fired back in the April 2 filing, claiming that Waste Management has shown "a complete lack of professionalism" and in terms of document production, is attempting to "sandbag" SAP.

"Waste Management is the one who started this lawsuit, yet it has still not substantially completed its production and just dumped over 8.6 million pages of documents on SAP in the last two weeks," it states.

Waste Management and SAP did not immediately respond to requests for comment.

The trial date for the case is currently set for October, although SAP is asking the court to push the date back to 2010, according to another filing. Waste Management has weighed in against such a decision.
