Diplaying heirarchial relation between structures of given Business Object

Hi,

I want to view the hierarchial relationshsip between various sturtcure of Business object BUS1001006 (mATERIAL MASTER).

I go to sxda transcation and then enter all the required details like program type and program name for that business object. But then when I hit display it asks me to enetr data for input file type and input file name ? <b>What should I enter there ?</b> Why does it need input file parameter ?

Do I need to create some empty file on application server so tat data will get dispalyed in that emplty fiole or what ?
