EC171 - Details

• The SAP error message EC171 ("Separator lines can be inserted only in menus") typically occurs when you are trying to insert a separator line in a context where it is not allowed, such as in a screen or a report layout that does not support separator lines.
  
  Cause:
  The error arises because separator lines are a feature that is specifically designed for menu structures in SAP. They are used to visually separate different sections of a menu for better organization and clarity. If you attempt to add a separator line in a context that does not support it (like a report or a screen), SAP will throw this error.
  
  Solution:
  To resolve this error, you should ensure that you are only trying to insert separator lines in appropriate contexts, such as:
  
  Menus: Make sure you are working within a menu structure (like a transaction or a custom menu) where separator lines are allowed.
