Product Selection
Use
Product selection uses material determination functions to automatically propose a variety of substitute products based on your requirements, customer requirements, and product availability.
Features
When you enter a material in a sales order, the system checks whether you have set up product selection for this material. If so, it creates a list of possible alternatives, checking each to determine current stock availability, and whether the customer would accept it based on the product attributes.
For each valid substitute that if finds, the system creates a sub-item.
If there is not enough inventory for the alternatives to completely confirm the requested quantity, the system confirms the partial amount and transfers the open quantity to planning. (This depends on your
settings for the substitutes.)The system carries out a new product selection when you trigger the availability check on the main item, for example when you change a quantity or date. Depending on the
substitution reason that you specify, substitutes are also redetermined in the delivery.
