Of course...
I followed the steps of this tutorial of Judson Wickham http://scn.sap.com/community/business-bydesign/blog/2012/05/27/epic-tutorial--mass-load-extension-data-to-a-bydesign-business-object-post-implementation and the second part http://scn.sap.com/community/business-bydesign/blog/2012/05/27/epic-tutorial-part-2--mass-load-data-to-extension-fields-post-implementation, it's a good tutorial, but I don't know why I can't load data, in other words, at the moment load, I can't see the information.
I hope you can help me.
Thank you so much.
Regards.
