Passing the value from one table to another table

I am creating a system where I have to select the customer and then process his order. Since the customer is recurrent, I bring this information from the customer table and save it in a collection (it is in pages that I am creating the app), this in order to search among the various customers that the system has, and then start to create the order.

How can I pass the information of the customer that I select to the Customer field of the orders table? I explored the options in the actions and I can’t find how to do it. Thank you very much for your support

So after adding the record, the last step is just to update values in that record, right?
Many thanks

Go for it…give it a try. If the record exists in a table then you can create an action to add the data you need to another table
