Hi All,

 

A customer following the Concurrent Engineering process reported an issue when part numbers are changed due to new design updates while the Shop Order is in Started status. The original part is serialized, and during manual receiving, when the source of the receive, part is switched to a substitute, the system shows the error: “Substituting for a Serialized Part not allowed.”

This was reproduced in both APP10 Regional Test LKP and IFS Cloud 25R1 Test CMB environments.

 

Upon reviewing the product documentation (Receive Substitute Part page), it is clearly mentioned under the prerequisites that: “The original part should not be a serialized part.”

Business Impact:

In Aerospace assembly manufacturing, shop orders often remain open for several weeks, and design changes occur frequently. Therefore, the ability to use substitute functionality for both serialized and non-serialized parts is critical for business operations. Currently, the substitute functionality works as expected for non-serialized parts but not for serialized ones.

The customer has requested clarification on the reason behind restricting substitute functionality for serialized parts during Shop Order receiving.

Could you please advise on the reasoning for this restriction and whether there are any recommended approaches or alternatives to address this requirement?

Thank you 

Explanation for Receive Substitute Part

This activity is used to receive a substitute part. However, if the receiving substitute part is equal to a shop order part and/or one of its by-products, then you will not be able to receive it as a substitute part. For catch-unit-enabled substitute parts, you must enter the catch unit.

Prerequisites

This activity requires that:

  • The material must be issued, and operations must be reported.
  • The original part should not be a serialized part.
  • The original part and the substitute part must have the same tracking definition (for both serial and lot tracking) in the part catalog.
  • If the order is connected to a control plan for which the Receipt Not Allowed check box is selected, the control plan analysis needs to be confirmed, and all-time triggers need to be stopped.
  • The part to be received must not belong to shop order part and/or be a by-product of the shop order.

The restriction is not a bug; it’s by design to preserve serialization traceability and regulatory compliance.
