• What is the cause and solution for SAP error message UGMD_TOOLS390 - Object is too large for shared memory ?

  The SAP error message UGMD_TOOLS390, which states "Object is too large for shared memory," typically occurs when an operation attempts to load or process an object that exceeds the limits set for shared memory in the SAP system. This can happen in various scenarios, such as when dealing with large data sets, reports, or when using certain tools that require shared memory for processing.
  Causes:
  
  Large Data Objects: The object being processed (e.g., a report, table, or data set) is larger than the allocated shared memory limit.
  Configuration Limits: The shared memory settings in the SAP system may not be configured to handle large objects.
  System Resource Constraints: The system may be under heavy load or may not have sufficient resources allocated to handle large operations.
  
  Solutions:
  
  
  Increase Shared Memory Limits:
  
  You can increase the shared memory limits in the SAP system configuration. This is typically done by adjusting the parameters in the instance profile (e.g., abap/heap_area_total, abap/heap_area_dia, abap/heap_area_nondia).
  After making changes, restart the SAP instance for the new settings to take effect.
  
  
  
  Optimize Data Processing:
  
  If possible, try to break down the large object into smaller chunks that can be processed individually.
  Use selection criteria to limit the amount of data being processed at one time.
  
  
  
  Check System Resources:
  
  Monitor the system's memory usage and performance. Ensure that the server has adequate physical memory and that other processes are not consuming excessive resources.
  
  
  
  Review SAP Notes:
  
  Check the SAP Support Portal for any relevant SAP Notes that may address this specific error or provide additional guidance on configuration settings.
  
  
  
  Consult with Basis Team:
  
  If you are not able to resolve the issue, consult with your SAP Basis team. They can provide insights into system configuration and performance tuning.
  
  
  
  Related Information:
  
  SAP Memory Management: Understanding how SAP manages memory can help in configuring the system appropriately. SAP uses different types of memory (shared memory, heap memory, etc.) for various operations.
  Transaction Codes: You can use transaction codes like RZ10 to modify instance profiles and RZ11 to check and change profile parameters dynamically.
  Performance Monitoring: Use transaction codes like ST02 (Tune Summary) and ST04 (Database Performance Analysis) to monitor memory usage and performance issues.
  
  By addressing the shared memory configuration and optimizing data processing, you should be able to resolve the UGMD_TOOLS390 error effectively.
