Is there a way to update global table of production scheduling dynamiclly ?

Hello,Everyone ! I am trying to modeling the Production Scheduling.

The model runs as the follows.

Different steps ,different machines and different items.The items enters into different machine according to the Global Table- "Steps ".The numbers in table represent which machine items would enter.

Besides,another ''Global Table -"Process time" maches the time of each step .

And in order to realize this,I used the item list to control the steps and the number of machine .

As we all know,new order mighIn arrive and the ''Global Table" should be changed .So how to update the Global Table dynamiclly to control the machine and time at some point when new orders arrive?

Is it possible that Users Events help?

Thank you very much for your attention!

You can clone a new table to an old table. When you do this, depends on the time, production conditions, or events. If you want to change it dynamically, you can use a user event or Process Flow. For production conditions I would collect event tokens in Process Flow, batch them and update the table.

Table oldPlan = Table(“yourPlan”);
Table newPlan = Table(“newPlan”);
newPlan.cloneTo(oldPlane);

@Jörg Vogel

Thank you very much for your advice.

I have tried to reedit the question as you said and post the small model .Besides I put your idea into my model ,the"New plan" global table really replace "Old plan" and update dynamiclly as what I need. However,there is another question occured.The "New plan" was cloned to"Old plan" but I don't know how to restore the "Old plan"when I reset the model.

Thank you again for your answer!

There are OnReset triggers in every 3D-objects, and there are Model triggers in the toolbox. You can write the code above in opposite action into an OnReset trigger. Process Flow needs a running model, an OnReset trigger needs only the OnReset button in the control dashboard to be activated.
