• What is the cause and solution for SAP error message KQ323 - Cost component structure & active: Only new entries allowed ?

  The SAP error message KQ323, which states "Cost component structure & active: Only new entries allowed," typically occurs when you are trying to make changes to an existing cost component structure that is currently active. This error is common in the context of controlling (CO) and product costing modules in SAP.
  Cause:
  The error arises because the cost component structure you are trying to modify is already active in the system. In SAP, once a cost component structure is activated, it is locked for changes to ensure data integrity and consistency in cost calculations. This means that you can only add new entries to the structure, but you cannot modify or delete existing ones.
  Solution:
  To resolve this error, you can follow these steps:
  
  
  Create a New Cost Component Structure:
  
  If you need to make changes, consider creating a new cost component structure instead of modifying the existing one. You can copy the existing structure and then make the necessary adjustments.
  
  
  
  Deactivate the Existing Structure:
  
  If you must modify the existing structure, you will need to deactivate it first. This can typically be done in the configuration settings. However, be cautious with this approach, as it may affect existing cost calculations and reporting.
  
  
  
  Check Dependencies:
  
  Before making changes, check if there are any dependencies or active processes that rely on the current cost component structure. Ensure that deactivating or modifying it will not disrupt ongoing operations.
  
  
  
  Consult Documentation:
  
  Refer to SAP documentation or your organization's internal guidelines for managing cost component structures. This can provide insights into best practices and potential impacts of changes.
