Hi Rick,
according to my analysis when deadline 'latest end` triggers after this process control step executes which will obsolete the current work item and re direct to workflow form there it will re execute agent logic and regenerate for next agent.
i can calculate next agent with standard FM ' SWW_WI_AGENTS_READ' with latest workitem id but for last approved person for last workitem it is showing as WF-BATCH.
i hope you will get my scenario.
Thanks,
Idris Ahmed Khan.
