SAP TM Transportation lane

Hello All,

I need to update some extra Z fields when a new TLANE is created. i have enhanced the TLANE BO, also created a Z determination to update those Z fields, but its not getting triggered. I have updated all the triggering properties.

Secondly I have also set up a PPF action when ever a TLANE is created,which will trigger a work flow. The same is also not getting triggered. Is there any specific thing i need to do or i am missing something here.

Please help.
