  Open the Data Dictionary (SE11):
  
  Go to transaction SE11 in your SAP system.

  Enter the name of the table to which you want to append fields and click on the "Display" button.
  
  
  
  Create Append Structure:
  
  Click on the "Append Structure" button (or navigate to the "Append" option in the menu).
  In the dialog that appears, you need to enter a name for the append structure. The name should follow the naming conventions of your organization (usually starts with "Z" or "Y" for custom objects).
  
  
  
  Define Fields:
  
  After entering a valid name, you can define the fields you want to add to the table in the append structure.
  
  
  
  Activate the Append Structure:
  
  Once you have defined the fields, save and activate the append structure.
  
  
  
  Check for Errors:
  
  Ensure there are no other errors in your definition or activation process.
  
  
  
  Related Information:
