Under Catalog > "Hide buy button" you have the option of storing article numbers.
The buy button and the delivery time will then be hidden for these.
In this way, you can very quickly remove the Buy button from many products at once.
And: the programming works independently of the database table of the products - this means you can also block article numbers that are not yet in the store.
An example:
you would like to create and upload products in your merchandise management system, but they should not yet be purchased.
One solution would be to create the products, upload them, then laboriously go into each product and fiddle around in the hope that nobody clicks on buy in the meantime.
With our programming, however, you simply throw the article numbers into the input mask first, and then upload the products from your merchandise management system - they are displayed, but are immediately blocked for purchase.
