• What is the cause and solution for SAP error message KK450 - No manual changes to price or price unit of items with structure allowed ?

  The SAP error message KK450 ("No manual changes to price or price unit of items with structure allowed") typically occurs in the context of controlling (CO) and product costing when you attempt to manually change the price or price unit of a cost estimate that is based on a structured item (like a BOM or a routing). This restriction is in place to maintain the integrity of the cost structure, as manual changes could lead to inconsistencies.
  Cause:
  
  Structured Items: The item you are trying to change is part of a structured item (like a Bill of Materials (BOM) or a routing) where the pricing is derived from the components or operations.
  Costing Type: The cost estimate is likely set up in a way that does not allow manual adjustments to the price or price unit for structured items.
  Configuration Settings: The system configuration may restrict manual changes to ensure that the cost estimates reflect the actual costs derived from the components.
  
  Solution:
  
  Review Cost Estimate: Check the cost estimate to ensure that it is correctly set up. If you need to change the price, consider adjusting the prices of the components in the BOM or routing instead of the structured item itself.
  Use Standard Costing: If you are using standard costing, ensure that the standard prices of the components are updated as needed.
  Adjust Configuration: If necessary, consult with your SAP configuration team to see if the settings can be adjusted to allow manual changes, but be cautious as this may lead to inconsistencies.
  Recreate Cost Estimate: If you need to make significant changes, consider recreating the cost estimate after making the necessary adjustments to the components or structure.
  Consult Documentation: Refer to SAP documentation or help resources for specific guidance on handling structured items and cost estimates.
  
  Related Information:
  
  Transaction Codes: Familiarize yourself with relevant transaction codes such as CK11N (Create Cost Estimate), CK40N (Change Cost Estimate), and CK24 (Display Cost Estimate).
  SAP Notes: Check SAP Notes for any known issues or additional guidance related to this error message.
  User Roles: Ensure that you have the appropriate authorizations to make changes to cost estimates and structured items.
