Service Contract in IC Web Client

I configured a transaction in Transaction Launcher so that i can access Service Contract in PCUI (BUS2000112). When i click on the new link in the Navigation Bar i get an error that says that i got an error in the data flow.

Can anyone help me with this, i don't know what more i have to configure, or what abap developments i have to make in the Class that was created by transaction launcher.

Best regard.
