I created an extra role call retailer that has edit_shop_order capabilities. What I want to do is have retailer role only see completed orders that have they post_author as their user_id. Or at least can anyone tell me how to change the query result for edit.php/post_type=shop_order.
Please help I'm at a total lost I don't see any template file to override or action or filter hook. And no this post didn't help me.
