Model Randomness

Hello everyone.
I have a model that is being integrated into another one, but they will be run separately. I copied the nodes of the tree from one model to another in parts. First the tables, then the parameters, followed by the global variables.

I ran the models separately and they showed no randomness. The next step was to add the User Commands and at this stage there was randomness.

The user commands are independent and each model runs its own independent user command.

I did not change the order of the nodes in the tree from one model to the other.

Is there any way to know which elements inserted into the model actually change the randomness of the models?

By randomness do you mean unrepeatability/unpredictability? If both models are deterministic then when you merge them the result should still be deterministic.

If you mean desired randomness from streams then when you merge models the stream id of objects may change between models, so you won't get the same event progression for the same replication number as you did in separate models.
