質問 # 41
Which disadvantages should you keep in mind when you set the High Cardinality flag for a characteristic? Note: There are 2 correct answers to this question.
- A. You cannot use this characteristic as a navigation attribute for another characteristic.
- B. SID numbers are created at runtime which might negatively affetct the reporting performance
- C. You cannot load more than 2 billion master data records for this characteristic
- D. You cannot use navigation attributes for this characteristic
正解：B、D
解説：
* A. You cannot use navigation attributes for this characteristic: This is a disadvantage of setting the High Cardinality flag for a characteristic. A characteristic with high cardinality cannot be used as a navigation attribute for another characteristic, and therefore it cannot have navigation attributes itself12.
* C. SID numbers are created at runtime which might negatively affect the reporting performance: This is a disadvantage of setting the High Cardinality flag for a characteristic. A characteristic with high cardinality has no persistent SID values and no SID table, which means that the SID numbers are generated on the fly during query execution. This can have a negative impact on the reporting performance, especially if the characteristic is used in filters or aggregations13.

質問 # 44
You create a DataStore Object(advanced) using the Data Mart DataStore Object modeling property. Which behaviors are specific to this modelling property? Note: There are 2 correct answers to this question.
- A. Reporting is done based on a union of the inbound and active tables
- B. The change log table will be filled only after data activation
- C. Query result are shown only when data has been activated
- D. The records are treated as if all characteristics are in the key.
正解：A、D
解説：
* B. Reporting is done based on a union of the inbound and active tables: This is a behavior that is specific to the Data Mart DataStore Object modeling property. The query reads data from both the inbound table and the active table of the DataStore object, which means that it is not necessary to activate the data to be able to see all the data. The data read is consistent and stable, since data is only included up to the first inconsistent request12.
* D. The records are treated as if all characteristics are in the key: This is a behavior that is specific to the Data Mart DataStore Object modeling property. No keys can be specified for this type of DataStore object, but when the data is activated, it is grouped according to the aggregation behavior of all characteristics. Therefore, key figures cannot be overwritten and only additive deltas can be loaded12.

質問 # 54
For InfoObject "ADDRESS" the High Cardinality flag has been set. However "ADDRESS" has an attribute
"CITY" without the High Cardinality flag. What is the effect on SID values in this scenario?
- A. SID values are generated when data for InfoObject "ADDRESS" is loaded.
- B. SID values are generated when InfoObject "CITY" is activated.
- C. SID values are generated when InfoObject "ADDRESS" is activated.
- D. SID values are not stored for InfoObject "ADDRESS".
正解：A
解説：
In SAP BW (Business Warehouse), the concept ofHigh Cardinalityplays a crucial role in determining how data is stored and managed for InfoObjects. Let's break down the scenario described in the question and analyze the effects on SID (Surrogate ID) values:
* InfoObject: An InfoObject is a basic building block in SAP BW, representing a business entity like
"ADDRESS" or "CITY".
* High Cardinality Flag: When this flag is set for an InfoObject, it indicates that the InfoObject has a very large number of distinct values (high cardinality). This affects how SIDs are generated and managed.
* SID (Surrogate ID): A unique identifier assigned to each distinct value of an InfoObject. SIDs are used to optimize query performance and reduce storage requirements.
* InfoObject "ADDRESS": The High Cardinality flag is set for this InfoObject. This means that the system expects a large number of distinct values for "ADDRESS". As a result, SID generation for
"ADDRESS" is deferred until actual data is loaded into the system. This approach avoids unnecessary overhead during activation and ensures efficient storage.
* Attribute "CITY": This attribute does not have the High Cardinality flag set. Therefore, SIDs for
"CITY" will be generated when the InfoObject is activated, as is typical for standard InfoObjects without high cardinality.
* ForInfoObject "ADDRESS", since the High Cardinality flag is set,SID values are NOT generated during activation. Instead, they are generated dynamicallywhen data for "ADDRESS" is loadedinto the system. This behavior aligns with the design principle of high cardinality objects to defer SID generation until runtime.
* Forattribute "CITY", SID values are generated during activation because it does not have the High Cardinality flag set.
Key Concepts:Scenario Analysis:Effects on SID Values:Why Option D is Correct:The correct answer isD.
SID values are generated when data for InfoObject "ADDRESS" is loaded. This is consistent with the behavior of high cardinality InfoObjects in SAP BW. SID generation is deferred until data loading to optimize performance and storage.
* SAP BW Documentation on High Cardinality: SAP BW systems use the High Cardinality flag to manage large datasets efficiently. For high cardinality objects, SIDs are generated at runtime during data loading rather than during activation.
* SAP Note on SID Generation: SAP notes related to SID generation (e.g., Note 2008578) explain the behavior of high cardinality objects and their impact on SID management.
* SAP Data Fabric Best Practices: In scenarios involving high cardinality, deferring SID generation until data loading is recommended to ensure optimal performance and resource utilization.
References:By understanding the implications of the High Cardinality flag and its interaction with attributes, we can confidently conclude that SID values for "ADDRESS" are generated only when data is loaded.
