In SAP BW/4HANA, when using InfoObjects and their attributes, certain properties of the objects can restrict or prevent specific configurations. Let’s analyze each option to determine why B, C, and D are correct:
Explanation: If an InfoObject is flagged as "Attribute Only," it means that this object is designed exclusively to serve as an attribute for another InfoObject. Such objects cannot be used as navigational attributes because navigational attributes require additional functionality, such as being part of reporting and navigation paths.
[: In SAP BW/4HANA, the "Attribute Only" property is a restriction that prevents an InfoObject from being used in ways other than as a display attribute. This ensures that the object remains lightweight and focused on its intended purpose., , 2. High Cardinality is set in InfoObject B (Option C)Explanation: High cardinality indicates that the InfoObject has a large number of unique values relative to the dataset size. Navigational attributes typically require efficient indexing and aggregation, which becomes challenging with high-cardinality fields. Therefore, SAP BW/4HANA does not allow high-cardinality attributes to be used as navigational attributes., Reference: High-cardinality attributes are better suited for use cases like drill-downs or detailed analysis rather than navigation. The system enforces this restriction to optimize performance and avoid excessive memory consumption., , 3. InfoObject B is defined as a Key Figure (Option D)Explanation: Key Figures are numeric measures (e.g., sales amount, quantity) and are fundamentally different from characteristics (descriptive attributes). Since navigational attributes must be characteristics, an InfoObject defined as a Key Figure cannot be converted into a navigational attribute., Reference: In SAP BW/4HANA, Key Figures and Characteristics serve distinct roles in data modeling. Key Figures are used for calculations and aggregations, while Characteristics provide context and descriptive information., , 4. Data Type "Character String" is set in InfoObject A (Option A)Explanation: The data type of InfoObject A (the primary InfoObject) does not influence whether InfoObject B can be converted into a navigational attribute. The data type of InfoObject B (the attribute) is more relevant in this context., Reference: While the data type of InfoObject A may affect how the attribute is displayed or processed, it does not impose restrictions on converting InfoObject B into a navigational attribute., , 5. Conversion Routine "ALPHA" is set in InfoObject A (Option E)Explanation: Conversion routines like "ALPHA" are used to format or transform data during input/output operations. These routines do not impact the ability to convert an attribute into a navigational attribute., Reference: Conversion routines are applied at the field level and do not interfere with the structural properties required for navigational attributes., , ConclusionThe correct answers areB (Attribute Only is set in InfoObject B),C (High Cardinality is set in InfoObject B), andD (InfoObject B is defined as a Key Figure). These properties directly conflict with the requirements for navigational attributes in SAP BW/4HANA., , ]
