Question about EM Integration for Resource extractor

Hi experts,

I am in TM 9.1 and tried the newest scenario for Resource Tracking between TM and EM. When I created a resrouce in TM with EM relevant checked, the correspdonding Resource EH with Application Object Type RES30_RESOURCE will be created in EM. Here comes a question, does Resource have the same logic as Order(Freight)? Order uses PPF direct Output agents, but I did not find the similar thing for resource. Where can I find the logic for resource relavant check and post to EM logic? Any FM? BO action? PPF setting?

Thanks and regards,
