• What is the cause and solution for SAP error message /SMB/CM_CONVERSION121 - Duration of Data Preparation before saving is &1 sec ?

  The SAP error message /SMB/CM_CONVERSION121 indicates that the duration of data preparation before saving exceeds a certain threshold, which is specified by the value &1 sec. This message is typically related to performance issues during data processing in the SAP system, particularly in the context of the SAP Business One or SAP Business ByDesign environments.
  Cause:
  
  
  Long Processing Time: The data preparation process is taking longer than expected, which could be due to various factors such as:
  
  Large volumes of data being processed.
  Inefficient data processing logic or algorithms.
  System performance issues, such as high CPU or memory usage.
  Network latency or issues with database performance.
  
  
  
  Configuration Issues: There may be configuration settings that are not optimized for the current workload or data volume.
  
  
  Resource Constraints: The server may be under heavy load, or there may be insufficient resources (CPU, memory, I/O) available for the data preparation tasks.
  
  
  Solution:
  
  
  Performance Tuning:
  
  Analyze the performance of the system to identify bottlenecks. Use transaction codes like ST03N (Workload Analysis) or ST04 (Database Performance Analysis) to monitor performance.
  Optimize database queries and indexes to improve data retrieval times.
  
  
  
  Batch Processing:
  
  If processing large volumes of data, consider breaking the data into smaller batches to reduce the load on the system.
  
  
  
  System Resources:
  
  Check the server's resource utilization (CPU, memory, disk I/O) and consider upgrading hardware or optimizing resource allocation.
  Ensure that the database server is properly tuned for performance.
  
  
  
  Configuration Review:
  
  Review the configuration settings related to data processing and adjust them as necessary to improve performance.
  
  
  
  Monitoring and Logging:
  
  Enable detailed logging to capture more information about the data preparation process, which can help identify specific areas that are causing delays.
