TE as flow items within Astar Navigator, too many sources?

How many sources can you have in the Astar Navigator? I have 3 sources producing TE as flow items. All 3 sources have different arrival schedules imported from excel. Unfortunately, only one source is creating flow items.

FlexSim 18.0.3

There is no limit. You'll have to attach the model if you want someone to look into why the source isn't producing.

Your sources are all producing. If you click on them when the model is running you can see in the Statistics panel in Quick Properties that the Output and Content of each source are going up. Because you have a limited capacity on the downstream processor, most of the time a person is created inside a source and then can't immediately leave the source and waits inside the source until a spot opens up downstream.

That said, I would recommend you not use fixed resources and port connections for controlling people walking around. They have options to facilitate it, but they weren't designed with walking people in mind. I would recommend using Process Flow to control the people. I've attached a sample model with two different ways of doing this.
