What is data quality? Within SAP, data quality is defined as postal validation, duplicate checking, and error tolerant searching. Postal Validation enhances address information by comparing data against address directories provided from local postal authorities around the world. Duplicate Check avoids duplicate entries by scanning the database for potential duplicates before new customer data is committed to the database. Finally, Error Tolerant Searching provides flexibility by giving users the ability to conveniently search their SAP system for business information as required. Involvement of a data quality initiative helps you maintain a reliable source of information for all departments within your own organization while simultaneously maximizing interactions with your vendors, customers, and business partners.
