• What is the cause and solution for SAP error message MPE_CM_BOM026 - Usage &1 cannot be removed as it is used in a BOM ?

  The SAP error message MPE_CM_BOM026 indicates that you are trying to remove a usage from a Bill of Materials (BOM) that is currently in use. This typically occurs when you attempt to delete or modify a BOM usage that is still referenced by existing BOMs in the system.
  Cause:
  The error arises because:
  
  The specified usage (&1) is linked to one or more BOMs.
  SAP enforces data integrity, preventing the removal of a usage that is actively being utilized.
  
  Solution:
  To resolve this error, you can follow these steps:
  
  
  Check BOM Usage:
  
  Use transaction code CS03 (Display BOM) to check if the BOM is using the specified usage. You can enter the material number and plant to see the details.
  
  
  
  Identify Dependencies:
  
  If the usage is indeed in use, you will need to identify where it is being used. You can use transaction code CS15 (BOM Level Structure) to find all BOMs that reference the usage.
  
  
  
  Remove or Change BOMs:
  
  If you need to remove the usage, you must first either:
  
  Change the BOMs that are using this usage to a different one.
  Delete the BOMs that are using this usage if they are no longer needed.
  
  
  
  
  
  Delete or Change Usage:
  
  Once all dependencies are resolved, you can then proceed to delete or change the usage in the BOM.
  
  
  
  Check for Other References:
  
  Ensure that there are no other references to the usage in other areas of the system, such as routing or production orders.
  
  
  
  Related Information:
  
  BOM (Bill of Materials): A BOM is a comprehensive list of materials, components, and assemblies required to manufacture a product.
  Usage in BOM: The usage field in a BOM indicates the purpose for which the BOM is created (e.g., production, engineering, etc.). Different usages can be maintained for the same material.
  Transaction Codes:
  
  CS01: Create BOM
  CS02: Change BOM
  CS03: Display BOM
  CS15: BOM Level Structure
  CS12: BOM Comparison
  
  
  
  By following these steps, you should be able to resolve the MPE_CM_BOM026 error and manage your BOM usages effectively.
