Snoozing allows to hide products from Order now tab in various cases such as:
product is not currently available for re-ordering
is a seasonal product
is an inactive product or being phased out
To snooze a product, click on Snooze button in the Actions column next to the product, enter a period in days for which you want to hide the product and click Snooze.
This will set the status of the product to Snoozed and move it over to Snoozed tab out of your way, so you can focus on products that require your attention.
You can also Snooze indefinitely to hide the product until you manually go to Snoozed tab, open the product and click Unsnooze.
