• What is the cause and solution for SAP error message CPWB854 - Marking Obsolete is not possible. This BOM is used in Routing &1 ?

  The SAP error message CPWB854 indicates that you are trying to mark a Bill of Materials (BOM) as obsolete, but the system has detected that the BOM is currently being used in a routing. This restriction is in place to maintain data integrity, as marking a BOM as obsolete while it is still in use could lead to inconsistencies in production planning and execution.
  Cause:
  The primary cause of this error is that the BOM you are attempting to mark as obsolete is linked to one or more routings in the system. Routings define the sequence of operations required to produce a product, and they reference the BOM for the materials needed in those operations. If a BOM is in use in a routing, it cannot be marked as obsolete until the routing is updated or the BOM is removed from the routing.
  Solution:
  To resolve this error, you can follow these steps:
  
  
  Identify the Routing: Determine which routing(s) are using the BOM. The error message typically provides the routing number (indicated by &1). You can use transaction codes like CA03 (Display Routing) to view the routing details.
  
  
  Update the Routing: 
  
  If the BOM is no longer needed in the routing, you can either delete the reference to the BOM in the routing or replace it with a different BOM.
  If the routing is still valid but needs to reference a different BOM, you can create a new BOM and update the routing accordingly.
  
  
  
  Mark the BOM as Obsolete: Once the BOM is no longer referenced in any routing, you can proceed to mark it as obsolete.
  
  
  Check for Other Dependencies: Ensure that the BOM is not being used in other areas, such as production orders, sales orders, or other dependent objects. If it is, you will need to address those dependencies as well.

  By following these steps, you should be able to resolve the CPWB854 error and successfully mark the BOM as obsolete.
