• What is the cause and solution for SAP error message RSM2156 - Data target &1 contains only &2 requests old enough for reduction ?

  The SAP error message RSM2156 indicates that a data target (such as an InfoCube or DataStore Object) contains only a certain number of requests that are old enough to be eligible for reduction. This typically occurs in the context of data management processes, such as data archiving or data reduction in SAP BW (Business Warehouse).
  Cause:
  The error message is triggered when you attempt to reduce the data in a data target, but the only requests available for reduction are older than a specified threshold. This can happen if:
  
  The data target has been configured to retain data for a certain period, and the requests that are eligible for reduction do not meet the criteria.
  There are no newer requests available for reduction, or the requests that are available are not old enough to be considered for the reduction process.
  
  Solution:
  To resolve this issue, you can consider the following steps:
  
  
  Check the Data Retention Settings: Review the settings for data retention in the data target. Ensure that the settings align with your data management policies and that they allow for the reduction of older requests.
  
  
  Review the Requests: Use transaction codes like RSA1 (Data Warehousing Workbench) to check the requests in the data target. Identify which requests are available and their timestamps.
  
  
  Adjust Reduction Criteria: If necessary, adjust the criteria for data reduction to include more requests. This may involve changing the settings in the data target or the reduction process.
  
  
  Perform Data Load: If there are no eligible requests for reduction, consider loading new data into the data target. This will create new requests that may be eligible for future reduction.
  
  
  Manual Reduction: If automatic reduction is not possible, you may need to manually delete or archive older requests that are no longer needed.
  
  
  Consult Documentation: Refer to SAP documentation or help resources for specific guidance on managing data targets and performing data reduction.
  
  
  Related Information:
  
  Transaction Codes: Familiarize yourself with relevant transaction codes such as RSA1, RSD1, and RSMO for managing data targets and monitoring requests.
  Data Management Best Practices: Implement best practices for data management in SAP BW, including regular monitoring of data targets and requests.
  SAP Notes: Check for any relevant SAP Notes that may provide additional insights or solutions related to this error message.
  
  By following these steps, you should be able to address the RSM2156 error and manage your data targets effectively.
