• What is the cause and solution for SAP error message GM004 - Secondary cost postings to order & not supported ?

  The SAP error message GM004 ("Secondary cost postings to order & not supported") typically occurs in the context of controlling (CO) when trying to post secondary costs to an order. This error indicates that the system does not allow secondary cost postings to the specified order type or configuration.
  Cause:
  
  
  Order Type Configuration: The order type may not be configured to allow secondary cost postings. In SAP, certain order types are set up to only allow primary cost postings (e.g., direct costs) and not secondary costs (e.g., internal allocations).
  
  
  Cost Element Type: The cost element being used for the posting may be defined as a primary cost element, which cannot be used for secondary postings.
  
  
  Posting Type: The transaction you are trying to execute may not support secondary cost postings. For example, certain transactions are designed to handle only primary costs.
  
  
  System Settings: There may be specific settings in the controlling area or the order type that restrict secondary postings.
  
  
  Solution:
  
  
  Check Order Type Configuration: 
  
  Go to the configuration settings for the order type in the SAP system (Transaction code: OPL8).
  Ensure that the order type is set up to allow secondary cost postings.
  
  
  
  Review Cost Element:

  Ensure that it is defined as a secondary cost element if you intend to post secondary costs.
  
  
  
  Use Appropriate Transaction: 
  
  Ensure that you are using the correct transaction for posting secondary costs. For example, use the appropriate allocation transaction (e.g., KSU5 for assessments or KSV5 for distributions) instead of a direct posting transaction.
  
  
  
  Consult Documentation: 
  
  Review SAP documentation or consult with your SAP support team to understand the specific configurations and limitations related to your system.
