  The SAP error message CM_EHFND_FW_WFF130 indicates that there is an issue with a cron string used in the configuration of a scheduled job or task. The cron string is a time-based job scheduler in Unix-like operating systems, and it defines the schedule on which a job should run. The error message specifically states that one of the parts of the cron string is invalid.
  Cause:
  The error can occur due to several reasons:
  
  Incorrect Format: The cron string may not adhere to the expected format. A typical cron string consists of five fields (minute, hour, day of month, month, day of week) and can include special characters.
  Out of Range Values: One or more of the values in the cron string may be out of the acceptable range. For example, minutes should be between 0-59, hours between 0-23, days of the month between 1-31, months between 1-12, and days of the week between 0-7 (where both 0 and 7 represent Sunday).
  Invalid Characters: The cron string may contain invalid characters or syntax errors.
  Missing Parts: If the cron string is incomplete or missing parts, it can lead to this error.
  
  Solution:
  To resolve the error, you can take the following steps:
  
  
  Check the Cron String: Review the cron string for any syntax errors. Ensure that it follows the correct format:
  * * * * * command_to_execute
  Where each asterisk can be replaced with specific values or ranges.
  
  
  Validate Each Field: Ensure that each part of the cron string is within the valid range:
  
  Minute: 0-59
  Hour: 0-23
  Day of Month: 1-31
  Month: 1-12
  Day of Week: 0-7 (0 and 7 both represent Sunday)
  
  
  
  Use a Cron Expression Validator: There are online tools available that can help validate cron expressions. You can use these tools to check if your cron string is valid.
  
  
  Consult Documentation: Refer to the SAP documentation or help resources for specific guidelines on how to format cron strings in the context of your SAP application.
  
  
  Test with Simple Cron Strings: If you are unsure about the cron string, start with a simple one (e.g., * * * * * for every minute) and gradually modify it to meet your scheduling needs.
  
  
  Related Information:
  
  Cron Syntax: Understanding the syntax and structure of cron strings is crucial. Familiarize yourself with the various options and special characters (like ,, -, /, *, etc.) that can be used in cron expressions.
