getting completed process details using BPM API

Hi Experts,

is there any way to get the completed process details using BPM API or Analytics API for a specific process definition (in 7.31 SP10)?

my observations:

1. using getRunningProcessInstances(process_def_id) of ProcessInstanceManager, I can fetch running process instances.

but I need completed process instances.

Thanks in advance.

Best Regards
