Warehouse Task Creation when TU actions starts for a outbound delivery

Hi All,

We have requirement that when ever TU action ( Checkpoint Arrival + Save ) which is assigned for given outbound delivery triggers , Warehouse task for that particular delivery needs to trigger automatically through PPF. We can able to trigger WT automatically through PPF at the time of OD creation but we need to make this happen when TU comes inside the premises i.e TU action starts.

How can we achieve this ? . Please do needful help.

Thanks,
