  The SAP error message WD800 with the text:
  *800-899 reserved for messages which can be used in the trace
  Cause:
  This message indicates that message numbers in the range 800 to 899 are reserved internally by SAP for trace and debugging purposes. These message numbers are not intended to be used for custom or application messages. If you or a program tries to define or trigger a message with a number in this range, SAP will raise this error to prevent conflicts with system trace messages.
  Explanation:
  
  SAP uses message classes and message numbers to handle errors, warnings, and information messages.
  The message number range 800-899 is specifically reserved for system trace messages.
  Attempting to create or use messages in this range in your own message classes or code is not allowed.
  
  Solution:
  
  Do not use message numbers between 800 and 899 in your custom message classes.
  Choose message numbers outside this reserved range, typically from 001 to 799 or from 900 upwards.
  If you encounter this error during development or customization, check the message class and message number you are trying to use and change it to a valid number outside the reserved range.
  Review your message class in transaction SE91 and adjust the message numbers accordingly.
  
  Related Information:

  SAP documentation and guidelines specify reserved message number ranges.
  The reserved range 800-899 is used internally by SAP for trace messages, which help in debugging and system analysis.
