Error While Checking List Content Before Token Release in Object Process Flow?

Hi Team,

I am working on model using process flow where machine is pulling 1 token from buffer before starting process. There is also extra supply to buffer periodically. I want to consume extra supply from buffer first than regular supply and order should be place for replenishment once buffer content (list content) reaches to 0.

I am facing error while using wait for event activity which is checking the buffer content before placing the order. Can you help me to resolve it?

Thank you!

Because the list is set to be 'local', there is an instance of the list for each object attached to the instanced process flow. The main list isn't valid in this case and you have to listen to the respective instance of the list instead.

You can do this by specifying the path to that instance in the object field through custom code.

You can also link the list activity to a global list instead and partition the entries by the instance object to keep them separate.
