The table used for the tutorial - snwd_so_inv_item - doesn't seem to be filled via transaction SEPM_DG documented here: The NetWeaver Enterprise Procurement Model - An introduction. Is there a simple means to actually fill the table with data? And if not, could the tutorial(s) be rewritten to work with a table which actually contains generated data after running SEPM_DG? SNWD_SO_I would for example have data.
