SAP has admitted that a unit within the company did download information from Oracle's network, but says it hasn't accessed or used any of the material.
Last month Oracle opened a law suit against SAP, claiming that the German vendor had hacked into its systems and stolen customer and product information.
In a written statement, SAP said the company's TomorrowNow unit had carried out "inappropriate downloads", but that the information stayed in the TomorrowNow systems.
Henning Kagerman, chief executing of SAP, added that the company regrets the occurence.
The Oracle suit claimed that SAP was guilty of "corporate theft on a grand scale" by hacking Oracle's Web site and downloading information.
