• What is the cause and solution for SAP error message RSMSS_ANALYZER_MSG159 - Prerequisite check &1 returned more than &2 uncompressed requests. ?

  The SAP error message RSMSS_ANALYZER_MSG159 indicates that a prerequisite check has returned more than the allowed number of uncompressed requests. This typically occurs in the context of the SAP BW (Business Warehouse) system when you are trying to execute a process chain or data load that involves the analysis of requests in a data store.
  Cause:
  The error is triggered when the system checks the number of uncompressed requests in a specific InfoProvider (like an InfoCube or DataStore Object) and finds that the number exceeds the defined limit. This limit is set to prevent performance issues that can arise from processing too many uncompressed requests at once.
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Check the Number of Uncompressed Requests:
  
  Use transaction RSA1 to navigate to the relevant InfoProvider and check the number of uncompressed requests. You can do this by going to the "Manage" tab and looking at the requests.
  
  
  
  Compress Requests:
  
  If there are too many uncompressed requests, consider compressing them. You can do this by selecting the requests and using the "Compress" option. This will reduce the number of uncompressed requests and may resolve the error.
  
  
  
  Adjust the Limit:
  
  If you frequently encounter this issue and the number of uncompressed requests is generally high, you may want to consider adjusting the limit. This can be done in the BW system settings, but be cautious as increasing the limit may lead to performance degradation.
  
  
  
  Delete Old Requests:
  
  If there are old or unnecessary requests that can be deleted, consider removing them to free up space and reduce the number of uncompressed requests.
  
  
  
  Monitor and Optimize Data Loads:
  
  Review your data loading processes to ensure they are optimized. This includes checking for any unnecessary data loads or requests that can be avoided.
  
  
  
  Related Information:
  
  Transaction Codes: Use transaction codes like RSA1 (Data Warehousing Workbench) and RSMO (Manage Data Loads) to manage and monitor your data requests.
  SAP Notes: Check for any relevant SAP Notes that may provide additional insights or updates related to this error message.
  Performance Considerations: Always consider the performance implications of your actions, especially when dealing with large volumes of data in BW.
  
  By following these steps, you should be able to address the RSMSS_ANALYZER_MSG159 error and ensure smoother operation of your SAP BW processes.
