A product can be produced as "Make-to-Stock" and "Make-to-Order".

The "Identified Stock type" value that needs to be maintained in the product master for a product that can be produced as "make-to-stock" and "make-to-order" and is not batch managed is "Optional Specified Stock" (B). This type of stock is used when the customer specifies the batch or serial number of the product that they want to purchase, but the company does not need to track the batch or serial number in the system. This allows the company to be flexible and produce the product as either "make-to-stock" or "make-to-order", depending on customer demand.
