3 classes of Data

3 classes or types of data exist in an ERP system: Master Data Organizational Data Transactional Data Docsity.com

Organizational Data

Organizational Data : Data elements which model the organizational structure units in an enterprise. Examples: plants, warehouses, storage locations, divisions, distribution channels, sales organizations, etc. Arranged according to tasks (particular activities) and functions (overall responsibilities). Mapping actual organization units to appropriate SAP structural representation is key element in configuration. Organizational data is a more specific type of master data and is rarely changed. Before creating master data, organizational data must be in place.

Master Data

Master Data : relatively fixed, frequently used data that remains stable over a long period of time. Often shared between different functional areas, processes, and system modules. Examples: customer data (address, contact info, etc.), vendor data, material data, and more. Providing consistency and accuracy in master data with and across systems: role of master data management. In SAP managed by SAP Exchange Infrastructure (XI) (old name), Process Integration (PI) (new name). Docsity.com

Document Principle

Document Principle : Every transaction that writes data to underlying database creates a uniquely numbered electronic document. Each document contains information such as Person responsible (who?) Date and time of the transaction (when?) Commercial content (what?) Once created, a document cannot be deleted from the database. Key to preserving an audit trail.
