• What is the cause and solution for SAP error message TD151 - Too many main windows defined ?

  The SAP error message TD151 ("Too many main windows defined") typically occurs when you are working with SAPscript forms or Smart Forms and you have defined more main windows than the system allows. In SAPscript, a form can have only one main window, while Smart Forms can have multiple main windows, but there are still limits based on the design.
  
  Cause:
  
  Exceeding Limits: The error is triggered when the number of main windows defined in a form exceeds the allowed limit. For SAPscript, this is usually one main window, while Smart Forms can have multiple but still have a maximum limit.
  Incorrect Form Design: If you are trying to create a complex layout with multiple main windows without adhering to the design constraints, this error can occur.
  
  
  Solution:
  
  Review Form Design: Check the form you are working on (either SAPscript or Smart Forms) and ensure that you have the correct number of main windows defined.
