This post is from my friend Juan Pedro Vargas Fernández. He did some sample for factsheet in his project and he is very kind to let me post his documentation about the factsheet on this blog. So I thank him for that.
You can follow him at @ : http://twitter.com/juanpedrov
His documentation goes as follows.
Finally let me tell you that in part got based in the explanation of this article: https://www.sdn.sap.com/irj/scn/wiki?path=/display/CRM/How+to+display+a+z-table+in+an+assignment+block
That article explain how to display a z table without using all the BOL concept that I’d like to understand. I tried to used a standard BOL (PRPAdvSearch) but it didn’t work. Maybe I should try creating my own BOL, maybe next time.
