I have a button on an SO that redirects the user to a suitelet when clicked. Within the same suitelet, I have a button to that is supposed to open a new Inventory Transfer form based on the SO details. I am having issues with the inventory detail as the script is throwing an error that the inventory detail is non-existent. Claude says it's not possible, that I have to autocreate the inventory transfer and redirect the user to the inventory transfer in edit (which I can because all the require details are available in the SO) but I'd rather not save the inventory transfer automatically. Thanks in advance

You could create a record (custom record) instead. Script a button on that custom record if you want to transform it to an actual inv transfer.

The closest you can get via pure suitescript is deploying a script on the inventory detail and manipulating the subrecord from the client script

Thanks for your inputs. So if I understand correctly, I can't populate the inventory detail (without saving the record) unless I have another client script or manipulate the DOM?
