USMD1049
- Data model &1, entity type &2, relationship &3: Cardinality is invalid ?The SAP error message USMD1049 indicates that there is an issue with the cardinality of a relationship in a data model. This error typically arises in the context of SAP Master Data Governance (MDG) when defining or modifying data models, entities, and their relationships.
Cause: The error message USMD1049 is triggered when the cardinality defined for a relationship between two entity types is invalid. Cardinality defines the number of instances of one entity that can or must be associated with instances of another entity. Common cardinality definitions include: 1:1 (one-to-one) 1:N (one-to-many) N:1 (many-to-one) N:N (many-to-many) The error can occur due to several reasons: Incorrect Cardinality Definition: The cardinality defined in the data model does not conform to the logical relationships between the entities. Inconsistent Relationships: There may be conflicting definitions of relationships between the same entities in different parts of the model. Missing or Incorrect Configuration: The configuration of the entities or relationships may be incomplete or incorrect.
