  The SAP error message CNV049 typically relates to the data conversion process in SAP systems, particularly during data migration or transformation activities. This message indicates that a certain limit of log records has been reached during the execution of a data conversion program.
  Cause:
  The error message CNV049 is triggered when the number of log records generated during a data conversion process exceeds the predefined maximum limit. This can happen due to various reasons, such as:
  
  High Volume of Data: The data being processed is large, leading to a significant number of log entries.
  Inefficient Data Processing: The conversion logic may not be optimized, resulting in excessive logging.
  Configuration Settings: The maximum number of log records allowed may be set too low for the volume of data being processed.
  
  Solution:
  To resolve the CNV049 error, you can consider the following approaches:
  
  
  Increase the Maximum Log Records:
  
  You can adjust the configuration settings to allow for a higher number of log records. This typically involves changing parameters in the relevant configuration tables or settings in the data migration tool you are using.
  
  
  
  Optimize Data Processing:
  
  Review the data conversion logic to identify any inefficiencies. Optimize the code or logic to reduce the number of log entries generated.
  
  
  
  Batch Processing:
  
  If possible, break down the data conversion process into smaller batches. This can help manage the number of log records generated at any one time.
  
  
  
  Review Log Management:
  
  Implement a strategy for managing logs, such as archiving or deleting old log records, to ensure that the system does not reach its limits.
  
  
  
  Consult Documentation:
  
  Refer to the SAP documentation or notes related to the specific data conversion tool you are using for any additional configuration options or best practices.
