• What is the cause and solution for SAP error message TD123 - Main window & cannot be deleted ?

  The SAP error message TD123, which states "Main window & cannot be deleted," typically occurs in the context of SAPscript or Smart Forms when you are trying to delete a main window from a form that is not allowed to be deleted. Here’s a breakdown of the cause, potential solutions, and related information:
  Cause:
  
  Main Window Restrictions: In SAPscript and Smart Forms, the main window is a critical component of the form layout. It is designed to hold the main content of the document. Deleting it can disrupt the structure of the form, which is why SAP restricts this action.
  Form Structure: The main window is essential for the proper functioning of the form. If it is deleted, the system cannot determine where to place the main content, leading to this error.
  
  Solution:
  
  Check Form Design: Instead of trying to delete the main window, consider modifying its properties or content. You can adjust the layout or the elements within the main window to achieve your desired outcome.
  Use Additional Windows: If you need to change the layout significantly, consider using additional windows (like secondary windows) to display different content without deleting the main window.
  Review Requirements: If you believe that the main window should be deleted based on your requirements, review the overall design of the form. You may need to redesign the form to accommodate your needs without removing the main window.
  Consult Documentation: Refer to SAP documentation or help resources for guidance on form design and the role of the main window in SAPscript or Smart Forms.
  
  Related Information:
  
  SAPscript vs. Smart Forms: Understand the differences between SAPscript and Smart Forms, as the handling of windows and layout may vary between the two.
  Form Maintenance: Familiarize yourself with the form maintenance transaction codes (e.g., SMARTFORMS for Smart Forms and SE71 for SAPscript) to navigate and modify forms effectively.
  SAP Notes: Check for any relevant SAP Notes that might address specific issues or enhancements related to form design and error messages.
  
  If you continue to face issues or if the error persists despite following the above solutions, consider reaching out to your SAP support team or consulting with an SAP expert for further assistance.
