• What is the cause and solution for SAP error message /ACCGO/MCK_MAINT390 - A CBC is already attached to commodity item &1 ?

  The SAP error message /ACCGO/MCK_MAINT390 A CBC is already attached to commodity item &1 typically occurs in the context of managing commodity items in the SAP system, particularly when dealing with Commodity-Based Costing (CBC) in the SAP S/4HANA environment.
  Cause:
  This error indicates that the commodity item you are trying to work with (denoted by &1) already has a CBC (Commodity-Based Costing) assignment attached to it. In SAP, each commodity item can only have one CBC assignment at a time. Attempting to attach a new CBC to an item that already has one will trigger this error.
  Solution:
  To resolve this error, you can follow these steps:
  
  
  Check Existing CBC Assignment:
  
  Use transaction codes like /ACCGO/MCK_MAINT or relevant reports to check the current CBC assignment for the commodity item in question.
  Identify the existing CBC that is already attached to the item.
  
  
  
  Remove or Change Existing CBC:
  
  If you need to attach a new CBC, you will first need to remove the existing CBC assignment. This can typically be done in the same transaction where you manage CBC assignments.
  Alternatively, if the existing CBC is still relevant, consider whether you can modify it instead of creating a new one.
  
  
  
  Attach New CBC:
  
  Once the existing CBC is removed or modified, you can proceed to attach the new CBC to the commodity item.
  
  
  
  Consult Documentation:
  
  If you are unsure about the process, refer to the SAP documentation or help files related to Commodity-Based Costing for detailed instructions.
