Package status for an "IF_UJ_CUSTOM_LOGIC" badi

Hi gurus,

I developed an "IF_UJ_CUSTOM_LOGIC" badi which in its class it uses method "lo_ujo_wb->write_back", but even when this method is getting an error ( I assigned "et_message" parameter from "lo_ujo_wb->write_back" to "et_message" exporting parameter from "IF_UJ_CUSTOM_LOGIC~EXECUTE" method), the package status is "succeed".

How could I change the status of the package and show the error messages?.

Could you please help me on this?

Thanks!!

Ana
