• What is the cause and solution for SAP error message KQ307 - CComp must be assigned only to cost of goods mfd or only to S+D costs ?

  The SAP error message KQ307 indicates that a cost component (CComp) is incorrectly assigned in the context of cost accounting. Specifically, it states that a cost component must be assigned either to "Cost of Goods Manufactured" (COGM) or to "Sales and Distribution" (S+D) costs, but not both. This error typically arises during the configuration of cost component structures in the Controlling (CO) module, particularly when dealing with product costing.
  Cause:
  
  Incorrect Configuration: The cost component structure may have been incorrectly configured, leading to a situation where a cost component is assigned to both COGM and S+D costs.
  Cost Component Assignment: The assignment of cost components in the costing variant or cost component structure may not adhere to the rules set by SAP, which require clear categorization of costs.
  Master Data Issues: There may be inconsistencies in the master data related to the cost components or the cost object.
  
  Solution:
  
  
  Review Cost Component Structure:
  
  Go to the configuration settings for the cost component structure in SAP (Transaction code: OKTZ).
  Check the assignments of the cost components and ensure that each component is assigned correctly, either to COGM or S+D costs, but not both.
  
  
  
  Adjust Cost Component Assignments:
  
  If you find that a cost component is incorrectly assigned, modify the assignment to ensure compliance with the requirement.
  You can do this by selecting the appropriate cost component and changing its assignment in the cost component structure.
  
  
  
  Check Costing Variants:
  
  Review the costing variants (Transaction code: OKKN) to ensure that they are set up correctly and that the cost components are assigned as intended.
  
  
  
  Validate Master Data:
  
  Ensure that the master data for materials, cost centers, and other relevant objects is consistent and correctly configured.
  
  
  
  Testing:
  
  After making the necessary adjustments, perform a test run of the costing process to ensure that the error does not reoccur.
