How To Fix CNV_10020571 - Table &1 needs a lot of memory space for org. determination

CNV_10020571 - Overview

• Message type: E = Error

• Message class: CNV_10020 - Message class for package 10020

• Message number: 571

• Message text: Table &1 needs a lot of 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. The parameter
MEMORY_PER_TASK_BORDER_TO_YELLOW (transaction CNV_10020_PARAM) says
that the system must output a warning message when the storage
requirements reach &V4& kBytes.
If processing of the table is split up into a multitude of tasks and/or
if a multitude of tables that need a lot of memory space is processed
in parallel, the <zh>total</> amount of storage space required may be
so big that only a few jobs can be processed in parallel.

System Response

The program for processing the table &V1& will probably not terminate.
however it will take up a lot of memory space.

How to fix this error?

Make sure that no other jobs that require a lot of memory space run in
parallel while table &V1& is being processed.
If necessary, 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.

tables in transaction CNV_10020_MEMTMON. The documentation for this
transaction contains a detailed description of possible solutions for
this problem.</>

CNV_10020571 - Details

• The SAP error message CNV_10020571 indicates that a specific table (denoted as &1) requires a significant amount of memory space for organizational determination during a data migration or conversion process. This error typically arises in the context of SAP data migration projects, especially when using tools like SAP S/4HANA Migration Cockpit or SAP Landscape Transformation (SLT).
  
  Cause:
  
  Large Data Volume: The table in question may contain a large volume of data, which requires substantial memory for processing.
  Complexity of Organizational Structure: If the organizational structure is complex, the determination process may require more memory to handle the relationships and hierarchies.
  Insufficient Memory Allocation: The system may not have enough memory allocated to handle the operations being performed on the table.
  
  Configuration Issues: There may be configuration settings that are not optimized for handling large datasets.
  
  
  Solution:
  
  
  Increase Memory Allocation:
  
  Check and increase the memory settings for the SAP application server. This can be done by adjusting the parameters
