In my case I have 7-8 call activities of a parent process.
Basically I wan the see the 1 Process Instance = 1 Report for the analysis purpose. Someone please let me know the possible ways to do it.
To view a single process instance together with its call activity subprocess instances for reporting, you can use Operate’s call hierarchy navigation or the relevant APIs. I found the following relevant resources:
- Get familiar with Operate - navigating call activities
- Get call hierarchy API (8.8+)
- Get process instance by key (Operate API)
- Forum: Read Parent Instance from Sub ProcessInstance (CallActivity)
- Forum: How to get process instance history in Camunda 8.7?
- Best practices: Reporting about processes
Does this help? If not, can anyone from the community jump in?
