workflow - Activiti - Parent process of subprocess -

we using activiti workflow engine on scenario:

and act_ru_execution table shows 2 subprocess's 2 independent process's no parent:

is possible parent process of subprocess , how gets represented on activiti's database ? because not finding relation.

is possible pass variables of main process subprocess in our scenario ?

parent process

how in servicetask:

select process instance have sub process instance given process instance. note there maximum one such process instance can result of query. runtimeservice.createprocessinstancequery().subprocessinstanceid(subprocessinstanceid).list();

in database:

act_ru_execution there 2 attributes parent_id_ , super_exec_.

• parent_id_ id of execution in tree hierarchy in 1 process (e.g. parallel execution, ...)
• super_exec_ id of super execution in process/subprocess relation

example of act_ru_execution table of process parallel executions , 1 sub-process:

pass variables subprocess

manually in process definition or dynamically listener implementation.
