https://community.appian.com/discussions/f/process/38478/race-condition-while-appending-to-process-variable-arrayHi all, I have a doubt is there a possibility we could have a race condition problem when appending from parallel process nodes to the same pv array? I have a following situation: So, I am generating several documents in parallel. Some of them willen-USTelligent Community 12https://community.appian.com/thread/145155?ContentTypeID=1Fri, 07 Feb 2025 18:48:07 GMTd3a83456-d57b-489c-a84c-4e8267bb592a:281450f0-bba3-4023-b809-c8176917fbc2Stefan Helzle<p>Thank you for making this clear :-)</p><div style="clear:both;"></div>https://community.appian.com/thread/145154?ContentTypeID=1Fri, 07 Feb 2025 18:43:25 GMTd3a83456-d57b-489c-a84c-4e8267bb592a:5e49a528-2514-4686-8f7e-116e084dc1d2Peter Lewis<p>Yeah I wouldn&#39;t expect any issues with running append operations on PVs in parallel paths. Even thought they may both be executing in parallel, they still would save their results to the variable in sequence.</p><div style="clear:both;"></div>https://community.appian.com/thread/145150?ContentTypeID=1Fri, 07 Feb 2025 15:43:29 GMTd3a83456-d57b-489c-a84c-4e8267bb592a:8260d8fd-da86-4a9e-9694-0550628986ecStefan Helzle<p>Process execution engines run the full process.

I would expect that parallel&nbsp;append operations on a PV should be OK.</p><div style="clear:both;"></div>
