Email is not triggered to employee responsible

Experts , help pls

Created action definition ‘ZDEMO_LEAD_EMAIL’ to send auto email to employee responsible upon saving lead document.

Method:CREATE_EMAIL_NOT

Structure: CRMC_PROC_TYPE

Field:PROCESS_TYPE

I made partner dependent in action definition and assigned partner function 14(employee responsible) .

Definition name:EXEC_METHODCALL_PPF

Implementation name : CRM_PSSC_EMAIL_NOT

But this method call is not triggering email to  employee responsible, instead , it is triggering email to contact person in the lead document.

Any idea which method I need to use instead of  CREATE_EMAIL_NOT?

Thanks in advance
