• What is the cause and solution for SAP error message CNV_CMIS_A_20282 - Huge table excluded for comparision: &1 ?

  The SAP error message CNV_CMIS_A_20282 indicates that a huge table has been excluded from comparison during a data migration or conversion process. This typically occurs in the context of SAP's data migration tools, such as the SAP S/4HANA Migration Cockpit or other data conversion scenarios.
  Cause:
  The error is triggered when the system identifies that a particular table is too large to be processed within the constraints set by the migration tool. This could be due to:
  
  The size of the table exceeding predefined limits for comparison.
  Performance considerations, as comparing very large tables can lead to significant resource consumption and slow down the migration process.
  Configuration settings that define thresholds for what constitutes a "huge" table.
  
  Solution:
  To resolve this issue, you can consider the following approaches:
  
  
  Review Configuration Settings:
  
  Check the configuration settings of the migration tool to see if there are parameters that define the maximum size of tables that can be compared. You may be able to adjust these settings to allow for larger tables.
  
  
  
  Exclude the Table from Comparison:
  
  If the table is not critical for the migration or if it can be handled separately, you can choose to exclude it from the comparison process. This may involve adjusting the migration strategy or plan.
  
  
  
  Split the Table:
  
  If feasible, consider splitting the data in the large table into smaller chunks that can be processed individually. This may require additional data handling logic.
  
  
  
  Optimize the Table:
  
  If the table contains unnecessary data, consider cleaning it up or archiving old records before the migration. This can reduce the size of the table and allow it to be included in the comparison.
  
  
  
  Consult Documentation:
  
  Refer to the official SAP documentation for the specific migration tool you are using. There may be specific guidelines or best practices for handling large tables.
  
  
  
  Contact SAP Support:
  
  If the issue persists or if you need further assistance, consider reaching out to SAP Support for guidance tailored to your specific scenario.
  
  
  
  Related Information:
  
  Migration Cockpit: Familiarize yourself with the SAP S/4HANA Migration Cockpit and its capabilities, as well as its limitations regarding data size.
  Performance Tuning: Look into performance tuning options for data migration processes, especially when dealing with large datasets.
  Data Model: Understand the data model of the source and target systems to identify which tables are essential for migration and which can be excluded or handled differently.
  
  By following these steps, you should be able to address the CNV_CMIS_A_20282 error and proceed with your data migration or conversion process effectively.
