Use

This function enables you to make use of an availability check. Because fully interchangeable parts have the same technically properties, you can use the interchangeable materials for cases in which there is no availability, even if another part has been reserved.

You can configure product selection so that the system performs the availability check for the inventory-managed manufacturer part that you enter in the sales order item and for all other interchangeable parts. If the entered part belongs to an MPN-MRP set , the system takes account of all the parts in the set during the availability check. If the entered part does not belong to a set, the system takes account of all the interchangeable materials.

Prerequisites

You have maintained MPN-MRP sets. For more information, see Creating and Editing MPN-MRP Sets .

In Customizing for Sales and Distribution, Result B is assigned to Substitution Reason 0009 . For more information, see Creating Substitution Reasons .

The document type of the sales document that you are using is assigned to a material determination procedure. For more information, see Assigning Procedures to Sales Document Types .

To avoid conflicts in the requirements transfer, the product selection is only allowed to take place if the availability is checked against the ATP quantityand not against the forecast. Therefore, in the master data of the parts in an FFF class, a strategy group is used to refer to a requirements class that is flagged for an availability check using ATP logic.As a rule, you can use Strategy Group 10 .

In Customizing for Sales and Distribution, the schedule line categories have been set up so that for sales document items the main item has schedule lines of type CD and the subitems have schedule lines of type CP . The Availability indicator has been set for schedule line type CP .

Features

The product selection of inventory-managed manufacturer part numbers is an enhancement to the standard product selection . The system assigns Category Type TAPA to the original item, which is a statistical item. The system looks at the quantity of interchangeable parts and determines the available ATP quantity for each part. The system adds a new subitem with Category Type TAN to each part that it determines. This item refers to the original item. The system repeats this process until it reaches the original order quantity or the quantity of interchangeable parts is exhausted.

The system looks at the originally entered part; the sequence in which it processes the parts is not fixed.

If an unconfirmed quantity remains at the end, the system annotates the original part.

The reservations generated by the system refer to the new items and are MRP-relevant for the selected interchangeable parts.
