• What is the cause and solution for SAP error message NAA191 - No characteristics are maintained for aggregation level &1 ?

  The SAP error message NAA191 indicates that there are no characteristics maintained for the specified aggregation level in the context of SAP BW (Business Warehouse) or SAP BW/4HANA. This error typically arises when you are trying to execute a query or a report that relies on an aggregation level that has not been properly defined or configured.
  Cause:
  
  Missing Characteristics: The aggregation level you are trying to use does not have any characteristics assigned to it. This means that the system does not know which dimensions or attributes to use for the aggregation.
  Incorrect Configuration: The aggregation level may not have been set up correctly in the BW system, or it may have been modified or deleted inadvertently.
  Data Model Changes: Changes in the underlying data model (like InfoObjects or InfoProviders) may have affected the aggregation level.
  
  Solution:
  
  
  Check Aggregation Level Configuration:
  
  Go to the Aggregation Level maintenance transaction (e.g., RSA1 in BW).
  Navigate to the Aggregation Levels section and find the specific aggregation level mentioned in the error message.
  Ensure that the necessary characteristics are assigned to the aggregation level.
  
  
  
  Add Characteristics:
  
  If characteristics are missing, you can add them by editing the aggregation level. Make sure to include all relevant dimensions that are required for your reporting needs.
  
  
  
  Validate Data Model:
  
  Ensure that the underlying data model (InfoObjects, InfoProviders) is intact and that there are no inconsistencies.
  Check if any changes have been made to the InfoObjects that might affect the aggregation level.
  
  
  
  Rebuild Aggregation Level:
  
  If the aggregation level is corrupted or incorrectly configured, consider deleting it and recreating it from scratch.
  
  
  
  Check Authorization:
  
  Ensure that you have the necessary authorizations to access the aggregation level and its characteristics.
