• What is the cause and solution for SAP error message IW521 - No changes possible to field "&1" (display mode) ?

  The SAP error message IW521, which states "No changes possible to field '&1' (display mode)," typically occurs in the context of the SAP Plant Maintenance (PM) module, particularly when you are trying to edit a maintenance order or a related object in a mode that does not allow changes.
  Cause:
  The error arises when you attempt to modify a field in a transaction that is currently in display mode. This can happen for several reasons:
  
  Display Mode: The transaction is opened in display mode, which does not allow any changes to be made to the fields.
  Authorization Issues: The user may not have the necessary authorizations to make changes to the specific field.
  Status of the Object: The maintenance order or object may be in a status that does not permit changes (e.g., completed, closed, or released).
  Field Configuration: The field may be configured as non-editable in the screen layout or field status settings.
  
  Solution:
  To resolve the IW521 error, you can take the following steps:
  
  
  Check Mode: Ensure that you are in the correct mode to make changes. If you need to edit the order, make sure you are in change mode (transaction code IW22 for changing maintenance orders).
  
  
  Check Object Status: Verify the status of the maintenance order. If it is in a status that does not allow changes, you may need to change the status to one that does (e.g., from "TECO" to "REL" if applicable).
  
  
  Authorization Check: Ensure that you have the necessary authorizations to edit the fields. You may need to contact your SAP security administrator to verify your permissions.
  
  
  Field Configuration: If the field is configured as non-editable, you may need to check the screen layout or field status group settings in the configuration. This may require access to the SAP Customizing Implementation Guide (IMG).
  
  
  Use the Correct Transaction: If you are trying to make changes to a specific field that is not editable in the current transaction, consider using a different transaction that allows for the required changes.
