The generation and comparison of a first time stamp and a second time stamp allows for the active operation of a mobile device that is intermittently connected to a middleware system. A document is created with a first time stamp, where this document relates to a particular activity associated with one or more objects. Affected object fields are also created to include a second time stamp. The first time stamp is updated to reflect a data request object and the second time stamp reflects when the affected object is adjusted on the back-end system. Until the second time stamp is later in time than the first time stamp, indicating successful processing of the data request object, the mobile device simulates the successful processing of the data request object to reflect the adjustment in a data object value.
