The Purchase Order header window contains a button labeled "Lines" that leads to the LINES block in a different window.

1. Add or modify the following triggers:

   • Trigger: PRE-FORM:

     app_window.set_window_position('HEADER','FIRST_WINDOW');

   • Trigger: WHEN-BUTTON-PRESSED on the LINES button:

     app_custom.open_window('LINES');
     

2. Modify APP_CUSTOM.OPEN_WINDOW as follows:

    IF wnd = 'LINES' THEN
      APP_WINDOW.SET_WINDOW_POSITION('LINES',
                          'CASCADE','HEADER');
      go_block('LINES');
   END IF;
   

   The styles available are:

   • CASCADE: Child window overlaps the parent window, offset to the right and down by 0.3" from the current position of the parent window. Usually used for detail windows.

   • RIGHT, BELOW: Child window opens to the right of, or below, the parent window without obscuring it.

   • OVERLAP: Detail window overlaps the parent window, aligned with its left edge, but offset down by 0.3".

   • CENTER: Window opens centered relative to another window. Usually used for modal windows.

   • FIRST_WINDOW: Position the window immediately below the toolbar. Usually used for the main entity window.
