Purpose
The system carries out product selection automatically in the sales order when you enter a material for which you have set product selection functions in
Customizing.Process Flow
If so, the system uses the requested delivery date in the header to determine a list of possible alternatives.
When a valid alternative is found, the system creates a sub-item for it, using the
item category that you have defined for the main material in Customizing.If there is not enough inventory for the alternatives to cover a required quantity, the system confirms only the available amount and ignores the rest. The main item contains information on the confirmed quantity of the sub-item, but is not relevant for planning. For this reason, the material shortage is not passed on to planning.
If you set the
material requirements planning indicator for one of the alternatives, however, the system creates an additional sub-item for this material, assigning it a confirmed quantity equal to zero, and a required quantity equal to the open quantity. Since this material is placed as the final alternative in the substitution, it captures any remaining quantities. The system takes this item into account and passes the material shortage on to planning.If you make any changes to the main item, the system automatically rechecks availability and recalculates prices for all items in the substitution list.
