How to create new lines to register information with a button?

Hello community! I have a question for you, I am making an interface for my company, this is to register part numbers that are received in a transaction to the warehouse of my company, here is an example of my screen so you have an idea:

The table on the right are the part numbers of the materials that exist and the table on the left are the pending receipts, in this screen you will select the receipt and the part numbers that were received there, making a list of them.


Let me know if you still have doubts about how it works, I would be very grateful if you could help me with this, blessings!

I would like to click on the “+” button to add more lines to register more part numbers to the transaction for example 59010.

Hello @Jared1419,

I am not 100% sure how you built your application, but I think your lines is a repeat item of an array

If yes, on click on the “+” button, you could have a workflow that change the variable (the array) you are using as repeat items for your lines. You can use the action “Change variable value”, and “insert at end”.

You can insert an empty object {} or an object with already the structure you want {"key1": "", "key2": "", ...}
