• What is the cause and solution for SAP error message WTY126 - Actions can only be carried out in change mode ?

  SAP Error Message:
  
  WTY126 - Actions can only be carried out in change mode
  
  Cause:
  This error occurs when you try to perform an action (such as editing, deleting, or making changes) on an object or transaction that is currently in display mode rather than change mode. SAP restricts certain operations to change mode to prevent unintended modifications.
  For example, if you open a work order, maintenance notification, or any master data in display mode and attempt to edit or perform an action that requires change authorization, the system will throw this error.
  
  Solution:
  To resolve the error WTY126, you need to switch the transaction or object from display mode to change mode before performing the desired action.
  Steps:
  
  
  Switch to Change Mode:
  
  Look for a button or menu option labeled "Change", "Edit", or similar in the application toolbar.
  Click this button to switch from display mode to change mode.
  
  
  
  Reopen the Object in Change Mode:
  
  If the transaction does not allow switching modes directly, exit the transaction.
  Reopen the object using the transaction code or menu option that opens it in change mode (e.g., use the "Change" transaction variant instead of "Display").
  
  
  
  Check User Authorizations:
  
  Ensure your user has the necessary authorizations to change the object.
  Lack of authorization might prevent switching to change mode.
  
  
  
  Save Changes:
  
  After switching to change mode, perform the required actions.
  Save your changes to avoid losing data.

  Display Mode: Read-only access, no modifications allowed.

  Authorization Objects:  
  
  Check authorization objects like I_OBJ (Object Type), I_ACT (Activity), and others relevant to the transaction.
