Message type: E = Error
Message class: MEMORY - Messages for memory management (BC-CST-MM)
Message number: 001
Message text: Currently used PROC memory
Current amount of PROC memory used by the server.
The system issues an error message and will not allow you to continue with this transaction until the error is resolved.
PROC memory is process-local memory which belongs to a work process and
which is not associated with a user session. Technically, PROC memory is
supplied to a work process via standard OS heap memory allocation, but
SAP ABAP application server keeps track of the consumed amount.
Above value is the sum of PROC memory across all work processes.

MEMORY001
- Currently used PROC memory ?The SAP error message MEMORY001 indicates that the currently used process memory has exceeded the limits set for the SAP system. This can occur due to various reasons, such as inefficient memory management, large data processing, or insufficient memory allocation for the SAP instance.
Causes:
- High Memory Consumption: The application or transaction being executed is consuming more memory than allocated.
- Large Data Sets: Processing large volumes of data can lead to increased memory usage.
- Memory Leaks: Inefficient coding or poorly designed programs can lead to memory not being released properly.
- Configuration Issues: The SAP instance may not be configured with adequate memory settings.
- Background Jobs: Running multiple background jobs simultaneously can lead to high memory usage.
Solutions:
Increase Memory Allocation:
- Adjust the memory settings in the SAP profile parameters (e.g.,
abap/heap_area_dia
,abap/heap_area_nondia
,abap/heap_area_total
).- Restart the SAP instance after making changes to the profile parameters.
Optimize ABAP Code:
- Review and optimize ABAP programs to ensure they are not consuming excessive memory.
- Use efficient data handling techniques, such as using internal tables wisely and releasing memory when no longer needed.
Monitor and Analyze Memory Usage:
- Use transaction codes like
ST02
(Tune Summary) andST04
(Database Performance) to monitor memory usage and identify bottlenecks.- Analyze memory dumps if available to identify the cause of high memory consumption.
Limit Concurrent Processes:
- Reduce the number of concurrent background jobs or user sessions if possible.
- Schedule heavy jobs during off-peak hours to minimize memory contention.
Upgrade Hardware:
- If the system consistently runs out of memory, consider upgrading the server hardware to provide more RAM.
Check for Memory Leaks:
- Use tools like the SAP Memory Inspector to identify and fix memory leaks in custom programs.
