Open your report and go to > Customize > Filters> Choose Detail Level and change it to 'All except Summary'.

You can do this for both the Open Sales Orders by Customer and the Open Sales Order by Item. 

If you want both Sales Orders and Invoices, go to > Customize > Filters> Posting Status and change it to 'Either'.

If you add your items to this report it will now show you the descriptions and totals.

Once you create the report you want, Memorize it.

Hope this has been helpful.
