How To Fix CNV_10020572 - Table &1 needs to much memory space for &2 &3

SAP Error Message - Details

• Message type: E = Error

• Message class: CNV_10020 - Message class for package 10020

• Message number: 572

• Message text: Table &1 needs to much memory space for &2 &3

What causes this issue?

The system found that &V2& &V3& was stored for the org. determination
for table &V1& (possibly as a subpath). This path needs around &V4&
kByte of memory space. However the amount of available memory space by
task is lower than this value.

System Response

The program for processing the table &V1& will probably terminate when
&V2& &V3& is loaded.

How to fix this error?

Reduce the required amount of data for &V2& &V3& and/or choose partial
determination or single determination for this path.

• What is the cause and solution for SAP error message CNV_10020572 - Table &1 needs to much memory space for &2 &3 ?

  The SAP error message CNV_10020572 indicates that a specific table (denoted as &1) requires too much memory space for the operation being performed, which is typically related to data conversion or migration processes. This error is often encountered during data migration activities, especially when using SAP's Data Migration tools or during system upgrades.
  Cause:
  
  Large Data Volume: The table in question may contain a large volume of data that exceeds the memory limits set for the operation.
  Insufficient Memory Allocation: The SAP system may not have enough memory allocated to handle the data processing for the specified table.
  Inefficient Data Processing: The way data is being processed (e.g., through inefficient queries or transformations) may lead to excessive memory usage.
  Configuration Issues: There may be configuration settings in the SAP system that limit memory usage for certain operations.
  
  Solution:
  
  
  Increase Memory Allocation:
  
  Adjust the memory settings in the SAP system. This can be done by modifying the instance profile parameters such as abap/heap_area_dia, abap/heap_area_nondia, and abap/heap_area_total.
  Ensure that the server has sufficient physical memory available.
  
  
  
  Optimize Data Processing:
  
  Review the data migration process to identify any inefficiencies. This may involve optimizing SQL queries or breaking down large operations into smaller batches.
  Consider using parallel processing if supported, to distribute the load.
  
  
  
  Data Volume Reduction:
  
  If possible, reduce the volume of data being processed at one time. This could involve filtering out unnecessary records or processing data in smaller chunks.
  
  
  
  Check for Locks and Performance Issues:
  
  Ensure that there are no locks on the table that could be causing delays or excessive memory usage.
  Monitor system performance to identify any bottlenecks that could be impacting memory usage.
  
  
  
  Consult SAP Notes:
  
  Check the SAP Support Portal for any relevant SAP Notes or updates that may address this specific error or provide additional guidance.
  
  
  
  System Upgrade:
  
  If the issue persists and is related to system limitations, consider upgrading the hardware or the SAP system itself to a version that can handle larger data volumes more efficiently.
  
  
  
  Related Information:
  
  SAP Notes: Always check for specific SAP Notes related to the error message for any patches or updates that may resolve the issue.
  Transaction Codes: Use transaction codes like ST22 (Dump Analysis) and SM21 (System Log) to analyze any dumps or logs that may provide more context on the error.
  Performance Monitoring: Utilize transaction ST03N (Workload Analysis) to monitor system performance and identify any areas that may need optimization.
  
  By following these steps, you should be able to address the CNV_10020572 error and ensure smoother data migration or processing activities in your SAP environment.
