• What is the cause and solution for SAP error message 37524 - Internal error in scanner - too little memory ?

  The SAP error message "37524 Internal error in scanner - too little memory" typically indicates that the SAP system is encountering a memory-related issue while trying to process a request, often during the execution of a report or transaction that requires significant resources.
  Causes:
  
  Insufficient Memory Allocation: The SAP application server may not have enough memory allocated to handle the current workload.
  Large Data Volume: The operation being performed may involve processing a large volume of data, which exceeds the available memory.
  Memory Leaks: There could be a memory leak in the application or in custom code that is consuming more memory than expected.
  Configuration Issues: Incorrect configuration settings for the SAP system can lead to inefficient memory usage.
  System Load: High system load or concurrent users may lead to memory exhaustion.
  
  Solutions:
  
  
  Increase Memory Allocation:
  
  Review and adjust the memory settings in the SAP profile parameters (e.g., abap/heap_area_total, abap/heap_area_dia, abap/heap_area_nondia).
  Ensure that the instance has sufficient memory resources allocated.
  
  
  
  Optimize Code:
  
  Review custom ABAP code for efficiency and memory usage. Look for opportunities to optimize data processing, such as using more efficient data structures or reducing the amount of data processed at once.
  
  
  
  Batch Processing:
  
  If the operation involves processing a large dataset, consider breaking it into smaller batches to reduce memory consumption.
  
  
  
  Monitor System Performance:
  
  Use transaction codes like ST02 (Tune Summary) and ST03 (Workload Analysis) to monitor memory usage and identify bottlenecks.
  Check for any long-running processes that may be consuming excessive memory.
  
  
  
  Check for Memory Leaks:
  
  Use tools like the ABAP Memory Inspector to identify potential memory leaks in custom programs.
  
  
  
  System Restart:
  
  In some cases, restarting the SAP application server can help clear memory and resolve temporary issues.
