Interface configuration method and system based on SAP (System Applications and Products in Data Processing) platform

The invention discloses an interface configuration method based on a SAP (System Applications and Products in Data Processing) platform. The interface configuration method comprises the following steps: calling all interface transmission table fields which possibly change in a SAP interface transmission table, extracting interface transmission table field conversion rules, and storing the interface transmission table field conversion rules into a rule cache region; independently making rule numbers for the interface transmission table field conversion rules of the rule cache region, and determining an interface transmission table field under each rule number; and establishing an interface configuration table in the SAP platform, calling the rule number and the corresponding interface transmission table field from the interface configuration table, and carrying out configuration to obtain a final interface. The interface configuration method has the beneficial effects that the regulation of a system interface
