Access information is received for a data sender interface accessible over a network and a data receiver interface accessible over the network. A set of navigation steps necessary to access data fields on the sender interface are determined. The data fields on the data sender interface are automatically mapped to data fields on the data receiver interface using at least one data mapping rule, such that a set of data field mappings is created. A data transfer scenario is generated using the set of navigation steps and the set of data field mappings, such that the data transfer scenario specifies a set of operations for transferring data from the sender interface to the receiver interface. The data transfer scenario is stored to computer readable media and can be executed any number of times to transfer data from the sending interface to the receiving interface.
