• What is the cause and solution for SAP error message ED088 - Messages in the range 900 to 999 are reserved for customers ?

  The SAP error message ED088, which states "Messages in the range 900 to 999 are reserved for customers," typically indicates that there is an attempt to use a message number in the reserved range that is meant for customer-specific messages. This error usually arises in the context of custom development or enhancements in SAP systems.
  Cause:
  
  
  Custom Message Usage: The error occurs when a program or function module tries to call a message that is defined in the range of 900 to 999, which is reserved for customer-defined messages. This can happen if:
  
  A developer has mistakenly referenced a message number in this range without defining it.
  There is a misconfiguration in the message handling logic of a custom program.
  
  
  
  Missing Message Definition: If a message is expected to be displayed but has not been defined in the message class, it will lead to this error.
  
  
  Solution:
  
  
  Define the Message: If you are developing custom functionality and need to use a message in the range of 900 to 999, you should define the message in a custom message class. You can do this by:
  
  Going to transaction SE91 (Message Class).
  Creating a new message class or using an existing one.
  Adding the required message with the appropriate number (900-999).
  
  
  
  Check Message Calls: Review the code where the error is triggered to ensure that the correct message number is being called. If a message is not defined, either define it or change the code to use a different message number that is already defined.
  
  
  Use Standard Messages: If possible, consider using standard SAP messages (those below 900) instead of creating new ones, unless there is a specific need for custom messages.
  
  
  Debugging: If you are unsure where the error is coming from, you can use the debugger to trace the execution of the program and identify the exact point where the message call is made.
  
  
  Related Information:
  
  Message Classes: In SAP, messages are organized into message classes, which are collections of messages that can be reused across programs. Each message class can contain messages numbered from 000 to 999, with 900-999 reserved for customer use.
