• What is the cause and solution for SAP error message UJA_EXCEPTION385 - Cannot get hierarchy &1 of dimension &2 ,Please check shared memory size ?

  The SAP error message UJA_EXCEPTION385 indicates that there is an issue with accessing a hierarchy in a specific dimension due to insufficient shared memory. This error typically occurs in the context of SAP BW (Business Warehouse) or SAP BI (Business Intelligence) when the system is unable to retrieve the required hierarchy data because the allocated shared memory is not sufficient.
  Cause:
  
  Insufficient Shared Memory: The primary cause of this error is that the shared memory allocated for the SAP system is not enough to handle the data being processed, particularly for hierarchies in dimensions.
  Large Hierarchies: If the hierarchy being accessed is particularly large or complex, it may require more memory than what is currently allocated.
  Configuration Issues: There may be configuration settings that limit the amount of shared memory available for processing.
  
  Solution:
  To resolve the UJA_EXCEPTION385 error, you can take the following steps:
  
  
  Increase Shared Memory Size:
  
  You can increase the shared memory size in the SAP system. This is typically done by adjusting the parameters in the instance profile.
  Look for parameters such as abap/shared_objects_size_MB and abap/heap_area_total and increase their values. The exact parameters may vary based on your SAP version and configuration.
  
  
  
  Check Hierarchy Configuration:
  
  Review the configuration of the hierarchy in the dimension to ensure it is optimized and does not contain unnecessary complexity or excessive data.
  
  
  
  Monitor Memory Usage:
  
  Use transaction codes like ST02 (Tune Summary) or SM04 (User Overview) to monitor memory usage and identify if there are any other processes consuming excessive memory.
  
  
  
  Restart the System:
  
  In some cases, restarting the SAP application server can help clear memory and resolve temporary issues.
  
  
  
  Consult SAP Notes:
  
  Check the SAP Support Portal for any relevant SAP Notes that may address this specific error or provide additional guidance.
  
  
  
  Contact SAP Support:

  Transaction Codes: Familiarize yourself with transaction codes like RSCUSTV10 (to check and adjust BW settings) and RSADMIN (to manage administrative settings).
  SAP Documentation: Refer to the official SAP documentation for detailed information on memory management and configuration settings.
  Performance Tuning: Regularly perform performance tuning and monitoring to ensure that your SAP BW system is running efficiently and can handle the required data loads.
  
  By following these steps, you should be able to resolve the UJA_EXCEPTION385 error and ensure that your SAP system can access the required hierarchies without memory issues.
