• What is the cause and solution for SAP error message AD738 - & & too long for logging (must be < &) ?

  The SAP error message AD738 typically indicates that a log entry or a message being processed is too long for the logging system to handle. The error message suggests that the length of the log entry exceeds the maximum allowed limit.
  Cause:
  
  
  Excessive Length: The primary cause of this error is that the log message or entry exceeds the maximum character limit set by the SAP system. This can happen when:
  
  A log message is generated with too much detail or information.
  A program or transaction is trying to log data that is inherently too long.
  
  
  
  Configuration Issues: Sometimes, the configuration settings for logging may not be properly set, leading to this error.
  
  
  Solution:
  
  
  Shorten Log Messages: Review the code or the process that generates the log messages. Try to limit the length of the messages being logged. This may involve:
  
  Trimming unnecessary details.
  Summarizing information instead of logging everything verbatim.
  
  
  
  Adjust Logging Configuration: If applicable, check the configuration settings for logging in your SAP system. Ensure that they are set to appropriate values that can accommodate the expected log message lengths.
  
  
  Error Handling: Implement error handling in your code to catch instances where log messages may exceed the limit and handle them gracefully, perhaps by logging a shorter message or an error code instead.
  
  
  Review Custom Code: If the error is occurring in custom ABAP code, review the relevant sections of the code to ensure that log messages are constructed properly and do not exceed the length limit.
  
  
  SAP Notes: Check the SAP Support Portal for any relevant SAP Notes that may address this specific error or provide guidance on logging practices.
  
  
  Related Information:
  
  SAP Documentation: Refer to the official SAP documentation for guidelines on logging practices and limitations.
  Transaction Codes: Use transaction codes like SLG1 (Application Log) to monitor logs and identify where the error is occurring.
  Performance Considerations: Be mindful of performance implications when logging, as excessive logging can impact system performance.
