• What is the cause and solution for SAP error message WER212 - Message number &1 does not exist in message class &2 ?

  Certainly! Here's a detailed explanation for the SAP error message:
  
  SAP Error Message:
  WER212 Message number &1 does not exist in message class &2
  
  Cause:
  This error occurs when the system tries to read or display a message with a specific message number (&1) from a message class (&2), but that message number does not exist in the specified message class.
  In other words, the program or transaction is referencing a message number that has not been defined or maintained in the given message class.
  
  Explanation:
  
  Message Class: A container in SAP where messages (errors, warnings, information) are stored.
  Message Number: A unique identifier within the message class for a specific message text.
  When a program calls MESSAGE <number> TYPE <type> ID <class>, SAP looks for the message text in the specified message class and number.
  If the message number is missing in the message class, SAP throws WER212.
  
  
  Common Scenarios:
  
  A developer or consultant references a message number that was never created in the message class.
  The message class was changed or transported incorrectly, missing some message numbers.
  Custom code or enhancement is calling a non-existent message.
  A typo in the message number or message class name.
  
  
  Solution:
  
  
  Check the Message Class and Number:
  
  Go to transaction SE91 (Message Maintenance).
  Enter the message class (&2) and check if the message number (&1) exists.
  
  
  
  Create or Correct the Message:
  
  If the message number does not exist, create it with the appropriate message text.
  If the message number exists but is incorrect, correct the message number in the program or code.
  
  
  
  Check the Program or Code:
  
  Identify where the message is called.
  Verify that the message class and number are correctly referenced.
  Correct any typos or wrong references.
  
  
  
  Transport and System Consistency:
  
  If the message exists in development but not in production, check transport requests.
  Ensure the message class and messages are transported properly.
  
  
  
  Debugging:
  
  Use the debugger to find the exact statement causing the error.
  Check the values of message class and number at runtime.
