Once I complete the physical inventory, how do I change the date on the input screen?

There is no way to backdate the physical inventory screen. You need to finish your counts and get them entered immediately.

Here are a couple videos I made about the Physical Inventory Count:

Greetings, @SDBG. 

Thanks for reaching out to the Community newcomer. I can provide some information to help answer your question about changing the date on the input screen. 

Yes, @BlackRock-Business is correct. There isn't a way to change the information once already entered into the system. I'll leave feedback for our Product Developers so they can consider this in the next available update. 

Also, check out this article about inventory that can help you in the future: Perform a physical inventory. 

I'm only a post away if I can be of additional assistance, please let me know. I'm always here to keep helping. Wishing you a wonderful rest of the week!
