  Certainly! Here's a detailed explanation for the SAP error message WER421 - Display mode not allowed for new elements:
  
  Error Message
  WER421: Display mode not allowed for new elements
  
  Cause
  This error occurs when you try to create a new element (such as a characteristic, class, or any master data object) in display mode instead of change mode. In SAP, new elements must be created or modified in change mode, and display mode is only for viewing existing elements.
  For example, if you open a transaction or screen in display mode and attempt to create a new entry, the system will prevent this and throw the WER421 error.
  
  When does it typically occur?
  
  When you open a transaction or master data object in display mode and try to create a new entry.
  When you use a transaction code or menu path that defaults to display mode.
  When user authorizations restrict you to display mode only.
  When a program or screen variant is set to display mode and you try to add new data.
  
  
  Solution
  
  
  Switch to Change Mode:
  
  Instead of opening the object in display mode, open it in change mode.
  For example, if you are using transaction CL02 (Change Class), use it instead of CL03 (Display Class).
  Similarly, for characteristics, use CT04 (Change Characteristic) instead of CT03 (Display Characteristic).
  
  
  
  Check User Authorizations:
  
  Ensure that your user has the necessary authorizations to create or change objects.
  If you only have display authorization, request the appropriate change authorization from your SAP security team.
  
  
  
  Check Transaction or Program Settings:
  
  If you are using a custom program or variant, verify that it is not forcing display mode.
  Adjust the program or variant to allow change mode if creation of new elements is required.
  
  
  
  Use Correct Transaction Codes:
  
  Always use the transaction codes designed for creating or changing objects when you want to add new elements.
