• What is the cause and solution for SAP error message CI_DRAFTPRD_MESSAGE045 - The unit of issue cannot be changed because product is used in a BOM ?

  The SAP error message CI_DRAFTPRD_MESSAGE045 indicates that you are trying to change the unit of issue for a product that is currently being used in a Bill of Materials (BOM). This restriction is in place because changing the unit of issue could affect the integrity of the BOM and the associated production processes.
  Cause:
  
  BOM Dependency: The product is part of a BOM, and changing the unit of issue could lead to inconsistencies in how the components are managed and consumed in production.
  Data Integrity: SAP enforces this restriction to maintain data integrity and ensure that all references to the product in the BOM remain valid.
  
  Solution:
  To resolve this error, you have a few options:
  
  
  Remove the Product from the BOM:
  
  If you need to change the unit of issue, you can temporarily remove the product from the BOM. After making the change, you can add it back to the BOM.
  Steps:
  
  Go to the BOM transaction (e.g., CS02 for changing BOM).
  Locate the BOM that includes the product.
  Remove the product from the BOM.
  Save the changes.
  Change the unit of issue for the product.
  Re-add the product to the BOM.
  
  
  
  
  
  Change the Unit of Issue in a Non-BOM Context:
  
  If the product is used in multiple BOMs, consider whether you can change the unit of issue in a different context or for a different product variant that is not currently in use.
  
  
  
  Consult with Stakeholders:
  
  Before making changes, consult with relevant stakeholders (e.g., production, planning, and engineering teams) to understand the implications of changing the unit of issue and to ensure that it aligns with business processes.
  
  
  
  Use a Different Product:
  
  If changing the unit of issue is critical and cannot be done while the product is in the BOM, consider creating a new product with the desired unit of issue and updating the BOM to use this new product.
  
  
  
  Related Information:
  
  BOM Management: Understanding how BOMs work in SAP is crucial. BOMs define the components needed to produce a product, and any changes to the components can affect production planning and execution.
  Unit of Issue: The unit of issue is the unit in which a product is sold or issued for production. It is important to ensure that this unit aligns with the production and inventory management processes.
  SAP Documentation: Refer to SAP Help documentation for more detailed information on BOM management and product master data.
  
  By following these steps, you should be able to resolve the error and make the necessary changes to the unit of issue for the product.
