How To Fix R7B075 - High Cardinality option set for InfoObject

SAP Error Message - Details

• Message type: E = Error

• Message class: R7B - BW Metadata (InfoCube, InfoObject, InfoObject catalog)

• Message number: 075

• Message text: High Cardinality option set for InfoObject

&DEFINITION&

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.

&USE&
Only use the High Cardinality option if you expect that the SID number
range of 2 billion will not be sufficient. Otherwise create the
characteristic without this property.
If the High Cardinality property is set, the characteristic does not
have persistent SID values or an SID table. This implies that it can
only be used in InfoProviders that store the key value and not the SID
value of the contained characteristics.
<ZH>Restrictions:</>
High cardinality characteristics cannot be used
in InfoCubes
as a compounding parent
as a navigation attribute
in hierarchies
The High Cardinality property is only supported for data type CHAR and
NUMC with length >= 10.
&DEPENDENCIES&
During reporting, SID values need to be created as local SIDs as
required. This can impact the response times of queries.

• What is the cause and solution for SAP error message R7B075 - High Cardinality option set for InfoObject ?

  The SAP error message R7B075 indicates that the High Cardinality option is set for an InfoObject in your SAP BW (Business Warehouse) system. This typically occurs when you are trying to use an InfoObject that has a high cardinality setting, which can lead to performance issues or complications in data processing.
  Cause:
  The High Cardinality option is used for InfoObjects that have a large number of unique values. When this option is enabled, it can affect the way data is stored and processed in the InfoProvider. The error message R7B075 usually arises in the following scenarios:
  
  Data Modeling Issues: The InfoObject is being used in a way that is not optimal for its high cardinality setting.
  Query Performance: Queries that involve high cardinality InfoObjects may run slowly or fail due to the large volume of unique values.
  Incompatibility with Certain Operations: Some operations or transformations may not be compatible with high cardinality InfoObjects.
  
  Solution:
  To resolve the R7B075 error, consider the following steps:
  
  
  Review the InfoObject Settings:
  
  Check if the High Cardinality option is necessary for the InfoObject. If the InfoObject does not require high cardinality, you can disable this option.
  To change the setting, go to the InfoObject in the Data Warehousing Workbench (transaction RSA1) and modify its properties.
  
  
  
  Optimize Data Model:
  
  If the InfoObject is required to have high cardinality, consider optimizing your data model. This may involve creating aggregates or using different InfoProviders that can handle high cardinality more efficiently.
  
  
  
  Query Optimization:
  
  Review the queries that are using the InfoObject. Try to limit the number of unique values being processed in a single query or use filters to reduce the dataset.
  
  
  
  Use of Characteristics:
  
  If applicable, consider using characteristics with lower cardinality or creating a hierarchy to manage the data more effectively.
  
  
  
  Consult Documentation:
  
  Refer to SAP documentation or notes related to high cardinality InfoObjects for best practices and recommendations.
  
  
  
  Testing:
  
  After making changes, test the queries and data loads to ensure that the performance is acceptable and that the error does not reoccur.
  
  
  
  Related Information:
  
  SAP Notes: Check for any relevant SAP Notes that may provide additional insights or fixes related to high cardinality InfoObjects.
  Performance Monitoring: Use transaction ST03N to monitor performance and identify any bottlenecks related to high cardinality InfoObjects.
  Data Warehousing Workbench: Familiarize yourself with the Data Warehousing Workbench (RSA1) for managing InfoObjects and InfoProviders effectively.
  
  By following these steps, you should be able to address the R7B075 error and improve the performance of your SAP BW system.
