Hi everyone
I try to update an existing invoice to add new products with line item.
To begin and for practice I try to change the current product by an other (eg 4Kg with 12Kg)

So I use the action step (Find Product Quickbooks) ans search for “12Kg”:

And then I put the corresponding product information in the Update Invoice step like this:
