• What is the cause and solution for SAP error message CKMLMV018 - Step &1: Packet &2 costed again with a reduced BOM ?

  The SAP error message CKMLMV018 typically occurs in the context of Material Ledger (ML) and is related to the costing process. This error indicates that a packet (or material) has been costed again using a reduced Bill of Materials (BOM). Here’s a breakdown of the cause, potential solutions, and related information:
  Cause:
  
  Changes in BOM: The error usually arises when there are changes made to the BOM after the initial costing has been performed. If the BOM is reduced (i.e., some components are removed), the system attempts to recalculate the cost based on the new BOM.
  Costing Run: The costing run may have been executed multiple times, and the system is trying to reprocess the costing with the updated BOM, which leads to inconsistencies.
  Material Ledger Settings: There may be issues with the configuration of the Material Ledger or the costing variant being used.
  
  Solution:
  
  Check BOM Changes: Review the changes made to the BOM. Ensure that the changes are intentional and that the new BOM is correctly defined.
  Reprocess Costing: If the BOM has been changed, you may need to reprocess the costing for the affected materials. This can be done by executing the costing run again.
  Review Costing Variants: Check the settings of the costing variant being used. Ensure that it is configured correctly to handle changes in BOM.
  Analyze Logs: Look at the logs generated during the costing run to identify any specific issues or inconsistencies that may have caused the error.
  Consult Documentation: Refer to SAP documentation or notes related to Material Ledger and costing to understand any specific requirements or limitations.
  
  Related Information:
  
  Transaction Codes: Familiarize yourself with relevant transaction codes such as CK11N (Create Cost Estimate), CK40N (Costing Run), and CKMLCP (Material Ledger Closing).
  SAP Notes: Check for any SAP Notes that may address this specific error or provide guidance on handling BOM changes in costing.
  Material Ledger Configuration: Ensure that the Material Ledger is properly configured for your organization’s requirements, including settings for actual costing and periodic unit price calculation.
  
  If the issue persists after following these steps, it may be beneficial to consult with your SAP support team or a consultant who specializes in SAP Material Ledger and costing processes.
