SAP Model Integrity

Information systems must serve the interests of the organisation that builds them.

SAP Systems provide the engine for data transfer within an organisation.

SAP Systems are assumed to be internally consistent with regard to data integrity. Interfaces with SAP systems must be built carefully to ensure that data consistency is kept. Control systems are required to provide feedback on the level of consistency between SAP systems and external systems.

Interface architectures must provide error handling procedures. Error handling should contain explicit monitoring and notification procedures.

Defects can cause a considerable amount of uncertainty in data processing. Defects are inevitable in modern business systems. Defects must by catalogued and monitored, which must include an assessment of defect risk. Defect management should be an explicit part of the management process.

SAP information system integrity must be monitored, and the effect of interfaces on the integrity of those systems must be monitored.
