• What is the cause and solution for SAP error message R7B073 - Master data access type &1 and high card. cannot be used in InfoObject &2 ?

  The SAP error message R7B073 indicates that there is an issue with the master data access type and high cardinality in relation to a specific InfoObject. This error typically arises in the context of SAP BW (Business Warehouse) or SAP BW/4HANA when dealing with master data and InfoObjects.
  Cause:
  
  High Cardinality: The error suggests that the InfoObject in question has a high cardinality, meaning it has a large number of unique values. This can lead to performance issues or complications in data processing.
  Incompatible Access Type: The master data access type specified (denoted by &1 in the error message) is not compatible with the InfoObject (denoted by &2). This could be due to the configuration settings of the InfoObject or the way the master data is structured.
  
  Solution:
  
  Review InfoObject Settings: Check the settings of the InfoObject to ensure that the master data access type is appropriate. You may need to adjust the settings to use a different access type that is compatible with high cardinality.
  Change Master Data Access Type: If the current access type is not suitable, consider changing it to a type that can handle high cardinality. This may involve modifying the InfoObject's properties in the SAP BW modeling tools.
  Optimize Master Data: If possible, consider optimizing the master data to reduce its cardinality. This could involve consolidating values or restructuring the data model.
  Consult Documentation: Refer to SAP documentation or notes related to the specific InfoObject and master data access types to understand the limitations and best practices.
  Testing: After making changes, test the InfoObject and the associated queries to ensure that the error is resolved and that performance is acceptable.
