• What is the cause and solution for SAP error message TD100 - Type &1 only permitted for main window &2 ?

  The SAP error message TD100, which states "Type &1 only permitted for main window &2," typically occurs in the context of SAP Smart Forms or SAPscript when there is an issue with the layout of the form. This error indicates that a specific type of window (like a secondary window) is being used incorrectly in a context where only the main window is allowed.
  Cause:
  The error is caused by trying to use a window type that is not permitted in a certain context. In SAP Smart Forms, there are different types of windows:
  
  Main Window: This is the primary window where the main content is displayed.
  Secondary Windows: These are additional windows that can be used for headers, footers, or other supplementary information.
  
  The error occurs when:
  
  You attempt to use a secondary window type in a place where only the main window is allowed.
  There is a misconfiguration in the form layout.
  
  Solution:
  To resolve the TD100 error, you can follow these steps:
  
  
  Check Window Types: Review the windows defined in your Smart Form or SAPscript. Ensure that you are using the correct window type in the appropriate context. The main window should be used for the primary content, while secondary windows should be used for additional information.
  
  
  Adjust Form Layout:
  
  Open the Smart Form or SAPscript in the SAP GUI.
  Navigate to the window that is causing the issue.
  Ensure that the content you are trying to place in a secondary window is appropriate for that window type.
  
  
  
  Reorganize Content: If you have content that needs to be displayed in a secondary window, consider moving it to the main window or adjusting the layout to fit the requirements of the main window.
  
  
  Test the Form: After making changes, test the form to ensure that the error is resolved and that the output is as expected.
  
  
  Consult Documentation: If you are unsure about the window types and their usage, refer to the SAP documentation or help resources for Smart Forms and SAPscript.
