Hi,
This can be achieved by using method: /SCWM/AU_GR_POST in processing details and for schedule condition: /SCWM/WHR_FULL_PACKED. So once a quant is packed it PPF Action will trigger to PGR. Then do the same thing to create the WT. find a schedule condition that checks for PGR complete then in processing details check method to create TO.
Hope this helps,
Faical
