• Message type: E = Error

• Message class: CNV_10020 - Message class for package 10020

• Message number: 570

• Message text: Table &1 needs too much memory space for org. determination

What causes this issue?

The system found that the paths stored for org. determination for the
table &V1& need a total of &V2& kByte of memory space. However only
&V3& kByte are available per task.

System Response

The program for processing the table &V1& will probably terminate.

How to fix this error?

Reduce the required amount of data for the determination paths needed
for processing table &V1&, and/or choose partial determination or
single determination for some of the paths.

• What is the cause and solution for SAP error message CNV_10020570 - Table &1 needs too much memory space for org. determination ?

  The SAP error message CNV_10020570 indicates that a specific table (denoted as &1) requires too much memory space for organizational determination during a data migration or conversion process. This error typically arises in the context of SAP data migration projects, particularly when using tools like the SAP S/4HANA Migration Cockpit or other data conversion tools.
  Cause:
  
  Large Data Volume: The table in question may contain a large volume of data, which can lead to excessive memory consumption during processing.
  Inefficient Data Structure: The structure of the table or the way data is organized may not be optimized for the operations being performed, leading to increased memory usage.
  Insufficient System Resources: The system may not have enough memory allocated to handle the operations required for organizational determination.
  Configuration Issues: There may be configuration settings that are not optimized for the current data volume or structure.
  
  Solution:
  
  Increase Memory Allocation: If possible, increase the memory allocation for the SAP system. This can be done by adjusting the instance profile parameters (e.g., abap/heap_area_total, abap/heap_area_dia, etc.) to provide more memory for the application server.
  Optimize Data: Review the data in the table to see if it can be optimized. This may involve:
  
  Archiving old or unnecessary data.
  Splitting large tables into smaller, more manageable ones.
  Ensuring that indexes are properly set up to improve access times.
  
  
  Batch Processing: If the operation can be performed in batches, consider breaking the data processing into smaller chunks to reduce memory usage at any one time.
  Check for Locks: Ensure that there are no locks on the table that could be causing delays or increased memory usage.
  Review Configuration: Check the configuration settings related to organizational determination and ensure they are appropriate for the data volume and structure.
  Use Alternative Tools: If the issue persists, consider using alternative data migration tools or methods that may handle large data volumes more efficiently.
  
  Related Information:
  
  SAP Notes: Check for any relevant SAP Notes that may address this specific error or provide guidance on memory management during data migration.
  System Monitoring: Use transaction codes like ST02 (Buffer Management) and ST04 (Database Performance) to monitor memory usage and identify bottlenecks.
  Documentation: Review the documentation for the specific migration tool you are using to understand its limitations and best practices for handling large datasets.
  
  If the problem continues after trying these solutions, it may be beneficial to consult with SAP support or a technical consultant who specializes in data migration and system performance.
