• What is the cause and solution for SAP error message DBMAN156 - InfoProvider &1 excluded because of pruning based on posted data ?

  The SAP error message DBMAN156 indicates that an InfoProvider has been excluded from a query or report due to pruning based on posted data. This typically occurs in the context of SAP BW (Business Warehouse) or SAP HANA when the system determines that there is no relevant data available for the specified query or report, leading to the exclusion of the InfoProvider to optimize performance.
  Cause:
  
  
  No Relevant Data: The primary cause of this error is that the InfoProvider does not contain any data that matches the selection criteria of the query. This can happen if:
  
  The data has not been loaded into the InfoProvider.
  The data has been filtered out based on the query's selection criteria.
  The InfoProvider is not activated or is in a state that prevents it from being used.
  
  
  
  Pruning Mechanism: SAP BW uses a pruning mechanism to enhance performance by excluding InfoProviders that do not contain relevant data for the query being executed. If the system determines that an InfoProvider has no relevant data, it will be excluded from the query execution.
  
  
  Solution:
  
  
  Check Data Load: Ensure that the data has been successfully loaded into the InfoProvider. You can do this by:
  
  Checking the data load process in the Data Warehousing Workbench.
  Verifying that the data is present in the InfoProvider using transaction codes like RSA1 or by running a query directly against the InfoProvider.
  
  
  
  Review Query Selection Criteria: Examine the selection criteria of the query to ensure that it is correctly defined and that it matches the data available in the InfoProvider. Adjust the filters if necessary.
  
  
  Activate InfoProvider: If the InfoProvider is not activated, activate it in the Data Warehousing Workbench (RSA1).
  
  
  Check for Data Pruning Settings: Review the settings related to data pruning in the query definition. You may need to adjust these settings if they are too restrictive.
  
  
  Analyze Query Performance: If the issue persists, consider analyzing the query performance and execution plan to identify any other potential issues that may be causing the InfoProvider to be excluded.
  
  
  Related Information:
  
  Transaction Codes: Use transaction codes like RSA1 (Data Warehousing Workbench), RSRT (Query Monitor), and RSRV (Query Validation) to troubleshoot and analyze the InfoProvider and query.
  SAP Notes: Check for relevant SAP Notes that may provide additional insights or solutions related to this error message.
  Documentation: Refer to SAP BW documentation for more information on InfoProviders, data loading, and query design best practices.
  
  By following these steps, you should be able to identify the cause of the DBMAN156 error and implement the necessary solutions to resolve it.
