I think that the first question you should ask yourself is: what is my process instance ? Is the review process as a whole or a single file under review ? In the former case, I'd just use attachments and process variables to keep track of them.

OTOH, if the review process of a single file is something more complicated, then one possibility is to create an independent (ie, not a sub-process) review process for those where that includes a reference to the main review process. You can then use messages sent from the file review process to the main review to keep track of the overall progress.

If you're building your own UI, those different approaches can be implemented in a way that the user is mostly unaware of.

Thanks for your answer, pmsevestre!

After reading your piece of advice, I think I will go for the second option: create an independent review process and keep track of the overall progress.

hi pmsevestre,
i have same question,
if the review process of a single file is something more complicated, then one possibility is to create an independent (ie, not a sub-process) review process for those where that includes a reference to the main review process. You can then use messages sent from the file review process to the main review to keep track of the overall progress.

how to reference to the main review process? how send message to the main review process
can you point some references or something that explain what you mean?

best regards

When starting the new process (probably from some kind of listener/service-task), add the parent-process/execution ID as a variable. Later on, in the child-process, you can use the variable to get hold of the parent process, using the EngineServices to access the API from a JavaDelegate or *Listener, using our API to send a message, set a variable or signal as usual.
