If you are using LiveCycle ES to search for processes using the adminui, then you may notice that not all processes are listed under the “Process Name – Version” drop-down list. Only processes which are activated in Workbench, and which have process instances in the TB_PROCESS_INSTANCE table in the database, will show up in this drop-down list.
Check that the process is activated in Workbench, and then you can run the following SQL query to verify that there are existing process instances for that process:
select distinct service_name, count(id) from tb_process_instance
group by service_name
order by service_name
