Improved SAP communications are provided by a terminator node that acts as termination on one end of the communication channel and links to the SAP server on the other end. A server device is also provided that optionally implements this terminator node and monitors communications between the SAP server and a client. The server device optionally condenses SAP application screens. The server device also simulates certain required responses to the SAP server to allow for a persistent session between a client and the SAP server when the actual connection may be intermittent. The server device also records required records for a transaction and provides them to a client for offline processing and then synchronizes stored offline transaction data from the client with the SAP server. The system may include a client device that optionally implements the terminator node to communicate with the server device or the SAP server.
