• What is the cause and solution for SAP error message DBMAN161 - InfoProvider &1 excluded because of pruning related to cold data ?

  The SAP error message DBMAN161 indicates that an InfoProvider has been excluded from processing due to "pruning" related to cold data. This typically occurs in the context of SAP BW (Business Warehouse) or SAP HANA, where data management strategies are employed to optimize performance and storage.
  Cause:
  
  Cold Data: The term "cold data" refers to data that is infrequently accessed or used. In SAP BW, cold data is often moved to a different storage tier to optimize performance and reduce costs.
  Pruning: Pruning is a process where certain data sets (like cold data) are excluded from processing to improve performance. If an InfoProvider is identified as containing only cold data, it may be excluded from certain operations, such as data extraction or reporting.
  Configuration Settings: The system may be configured to automatically exclude InfoProviders that are deemed to contain cold data based on certain criteria or thresholds.
  
  Solution:
  
  Review Data Access Patterns: Analyze the access patterns of the InfoProvider to determine if it is indeed cold data. If the data is still relevant for reporting or analysis, consider adjusting the data management strategy.
  Adjust Pruning Settings: If the exclusion of the InfoProvider is not desired, you may need to adjust the settings related to data pruning in the SAP BW or HANA configuration. This may involve changing the thresholds for what constitutes cold data.
  Data Lifecycle Management: Implement a data lifecycle management strategy that allows for better handling of cold data, ensuring that it can still be accessed when needed without impacting performance.
  Re-activate the InfoProvider: If the InfoProvider is still needed, you may need to manually re-activate it or adjust its status in the system to allow for processing.
  Consult Documentation: Refer to SAP documentation or support for specific instructions on managing cold data and pruning settings in your version of SAP BW or HANA.
  
  Related Information:
  
  SAP Notes: Check for any relevant SAP Notes that may provide additional insights or updates regarding this error message.
