Abstract: A system for parallel object modification is disclosed. A request receiving module receives a processing request released from a first project executed at a first project wave landscape of the enterprise resource planning application. A parallel processing module instantiates one or more objects for parallel execution at a second project wave landscape. An object modification determination module detects one or more scenarios of modification of the one or more objects corresponding to the first project wave landscape and the second project wave landscape respectively, wherein the one or more scenarios includes a conflict scenario, a semi-computerized scenario and a non-conflict scenario.
