How To Fix MPE_PLAN_RTG_VERS091 - Serialized object cannot be assigned to non-serialized routing

MPE_PLAN_RTG_VERS091 - Overview

• Message type: E = Error

• Message class: MPE_PLAN_RTG_VERS - Manage Production Routing Version

• Message number: 091

• Message text: Serialized object cannot be assigned to non-serialized routing

What causes this issue?

You are currently processing a shop floor routing for a non-serialized
product and are trying to assign an object that was created in the
context of a serialized product.
This is not possible: If an operation is created in the context of a
non-serialized product, it's operation activities only contain one
status and action schema (SAS) for non-serialized products, for example.
However, if the routing is created for a serialized product, the
operation activities require two status and action schemas; one for
non-serialized products and one for serialized products. Therefore, you
cannot assign the operation created for a non-serialized product to a
routing that contains a serialized product and vice versa. In addition,
for a serialized product, certain additional QM settings that are
required for production are automatically set and saved for the object
that are not required for non-serialized products.

System Response

The system cannot assign this object.

How to fix this error?

You can only assign objects that were created in the same context -
either for a non-serialized product or a serialized product.

Procedure for System Administrators

• What is the cause and solution for SAP error message MPE_PLAN_RTG_VERS091 - Serialized object cannot be assigned to non-serialized routing ?

  The SAP error message MPE_PLAN_RTG_VERS091 indicates that there is an issue with the assignment of a serialized object to a non-serialized routing. This typically occurs in the context of production planning and control, where serialized objects (like specific items or materials that have unique identifiers) are being incorrectly linked to routings that do not support serialization.
  
  Cause:
  
  Mismatch in Routing Type: The routing you are trying to assign the serialized object to is defined as a non-serialized routing. This means it does not support the tracking of individual serialized items.
  
  Configuration Issues: The configuration settings for the routing or the material may not be set up correctly to handle serialized items.
  Data Entry Errors: There may be an error in the data entry process where a serialized object is mistakenly linked to a routing that does not accommodate serialization.
  
  
  Solution:
  
  Check Routing Configuration: Review the routing configuration in the system. Ensure that the routing is set
