Running a Process having an Action item step with Escalation rules is failing with error "BPM-0543: An error occurred when sending the action item. Contact your site administrator. {0}".
If we remove the escalation rules from the step the process executes as expected.
Release : 16.0.1
Component : PPMBPM
This is caused by Missing scheduled Job Templates of Escalation jobs in CMN_SCH_JOBS table.
Run the following query to identify if you have the scheduled JOB Templates or not.
select * from cmn_scH_jobs where job_definition_id in (select id from cmn_sch_job_definitions
where job_code in ('BPM_ESC_ESCALATION','BPM_ESC_RESCHEDULE_ESC_JOB') );
If the query doesn't return any records, please reach out to Broadcom Support.
