Get Full Process History?

[Melissa Palmer]

Hi 

Using the Camunda API is there a way to get the full history for a whole process if you only have the current taskId and/or processInstanceId? 

Thanks

Hi Melissa,

You should be able to use the current processInstanceID, to get the ProcessInstance object, ( see: http://docs.camunda.org/7.2/api-references/rest/#process-instance-get-single-instance ) which will contain the ProcessDefinitionId.  Once you have the ProcessDefinitionId you can use this as a parameter to query for the history of the 'whole process' ( see: http://docs.camunda.org/7.2/api-references/rest/#history-get-process-instances-post )

Kind Regards

Gareth

Hi Melissa,

Using rest APIs
http://docs.camunda.org/7.2/api-references/rest/#history-get-task-historic

as you can see, you can query using processInstanceId as a parameter

Using java APIs
http://docs.camunda.org/7.2/api-references/javadoc/

HistoricTaskInstanceQuery processInstanceId(String processInstanceId)
Only select historic task instances for the given process instance.

Hi Gareth, and Hassan

Thanks for the feedback, however this isn't quite getting me what is needed. Most specifically when a process has a CallActivity to a sub-process. 

Using the API's (REST of Java) you only get the history for that processId and not the history for the sub-processes that we called from it (or before it... in the case where you are currently sitting within a sub-process node) 

Is there a way that one can use a processId (for a main or sub-process) which will get the history related to each other? 

Thanks

Hi Melissa,

If I understand you well. I think you can define a unique identifier as a process variable with the same name (for example: 'requestId') on both processes (main & sub). passing the value of it when calling a sub-process.

That way you can query by process variable name "the unique identifier"
