Hello,
I am working with inventory management database. I have two different tables where both have unique UPCs and a status selection. I am creating a third table that will only display products from both tables that are ready for sale i.e status is “Listed”.
I have created an automation that checks when status is changed to “listed” then find if that UPC doesn’t exist in product table then create a new field with that UPC. I run into duplicate entry problem. *** when I change a product to listed it will pop up in products list which is what I want but when I change the status to something else and then change it back to “listed” it will create a duplicate field which is not what I expect.***

No matter who much I played around with different conditions and values in find section of automation I still couldn’t figure it out.
