block outbound delivery creation on item level

Hello expert,

In our system the sales order would be created to outbound delivery automatically in certain defined schedule. But sometimes we want to manually allocate the stock to orders, due to parts availability issue. Therefore, we want to know:

Is there a way to excluded these material number from the auto jobrun (sales order -> outbound delivery)? such as change on material master level, or mass change on sales order item level?

Thanks for your help

Best regards,
