MDM solutions enable organizations to consolidate master data from multiple disparate systems into a central repository to establish a single source of truth. This eliminates duplicate, inconsistent, and inaccurate data. MDM solutions also standardize data, resolve errors and redundancies, and support data governance through tools for data ownership, stewardship, and maintenance of data integrity. SAP's standard master data management capabilities are limited and do not allow for business rules enforcement, role-based access controls, workflows, or easy management of complex master data screens and attributes. An external MDM solution can simplify SAP data processing by distributing it across departments, adding approval workflows, and integrating various data sources.
