Change to an Alternate Part

Explanation

This activity is used to replace a prime part on a work order material requisition line with a valid alternate part. An alternate part is a part that fulfills requirements (e.g., equivalent in performance, reliability or maintainability) and is interchangeable with a primary part.

There can be instances where the material to be used on the work order is out of stock or no longer utilizable. Responsible personnel, such as, maintenance planners, need to ensure the material is replaced in time so that the work can be carried out without any delays due to material shortages. One way of doing this is to raise a purchase requisition and order the parts. Another is to replace the prime part with a valid alternate part, as described in this activity description.

It is possible to replace all or part of the quantity of the primary part with a valid alternate by using the Change to Alternate dialog box. When this is done, material lines will be created for the alternate parts and added to the same material order to which the original material line belongs. You can then continue planning the material for the work order.

Note: If a material line which was created for an alternate part is deleted, the Quantity Required and Quantity Changed fields on the original line will be updated to reflect the change. If the original material line has been closed, only the Quantity Changed field will be updated.

Prerequisites

• A valid alternate part should be available in inventory, at the same site as the selected material order.
• The remaining quantity for the part on the material line should be more than zero. Remaining quantity is the required quantity minus both issued and reserved quantities for the part.
• The part on the material line should not have a pegged quantity.
• The part on the material line should not be a repair part or a rental tool.
• The material line should not have been created from a purchase requisition.
• The material line should not be closed.
• Change reasons should be defined in basic data, i.e., in the Maintenance Basic Data/Alternate Part Change Reason tab.

System Effects

• A material line will be created for the alternate part that was selected to replace the prime part. If different alternate parts were selected to replace the prime part, a material line is created per part. The new lines will be added to the material requisition order of the original material line.
• For the material lines that are created for the alternate parts, the Changes Line No field will be updated automatically with the order line number that was changed. The Change Reason field will be updated with the given change reason.
• For the original material line, the Quantity Changed field will be updated automatically with the quantity of the part that was replaced. The Quantity Required field will be reduced by the same amount.
