• What is the cause and solution for SAP error message CNV_20100145 - Multicopy indicator was set for table &1 ?

  The SAP error message CNV_20100145, which states "Multicopy indicator was set for table &1," typically occurs during data migration or conversion processes, particularly when using the SAP S/4HANA Migration Cockpit or similar tools. This error indicates that the system has detected that the multicopy indicator is set for a specific table, which can lead to issues during data processing.
  Cause:
  The multicopy indicator is a setting in SAP that allows multiple entries to be copied or processed simultaneously. However, certain tables may not support this feature due to their structure or the nature of the data they hold. When the multicopy indicator is set for a table that does not support it, the system raises this error to prevent potential data integrity issues.
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Check Table Settings: Identify the table mentioned in the error message (replace &1 with the actual table name). Review its settings in the Data Dictionary (transaction SE11) to confirm whether the multicopy indicator should be set.
  
  
  Adjust Multicopy Indicator: If the multicopy indicator is not appropriate for the table, you may need to adjust the settings. This can typically be done in the Data Migration or Conversion tool you are using. Ensure that the multicopy indicator is disabled for that specific table.
  
  
  Review Migration/Conversion Process: If you are using a migration tool, review the configuration and mapping settings to ensure that they align with the requirements of the target system.
  
  
  Consult Documentation: Refer to the SAP documentation or notes related to the specific migration or conversion process you are performing. There may be specific guidelines or prerequisites that need to be followed.
