Escalated workflow task showing WF-BATCH as Agent

Hello All,

I have requirement in report that i need to show last approved agent which approved by agent. Agent determination is based on Agent table.

in case of deadline escalation when latest end step executes system shows agent as "WF-BATCH" where last approved agent is expected according to level.

i am taking WI_AAGENT field form SWWWIHEAD table to show last approved agent.

i tried below update query in workflow but not sure it is correct or not.

UPDATE swwwihead

        SET WI_AAGENT = lw_agent-agent

        WHERE WI_ID EQ workitem_id

        AND WI_RH_TASK EQ task_id

        AND no_deadl EQ 'X'.

could you please advice on this.
