Add fields in output of ME59N Test Run

Hello,

I am using ME59N trsnaction to create purchase orders automatically from PR. But before creating those orders, I execute the transaction in Test Mode by selecting "Test Run" check box from selection screen.

Now, I want to add article number and description field in the output of this test run layout. Output has no button to select more fields in the layout.

How can i add those fields in the output?

Thanks & Regards
