  The SAP error message K9028, "There is no valid previous combination," typically occurs in the context of controlling (CO) when you are trying to perform a transaction that requires a valid previous combination of cost elements, cost centers, or other related data. This error can arise in various scenarios, such as during the posting of costs, planning, or reporting.
  Cause:
  
  Missing Data: The error often indicates that the system cannot find a valid combination of the required data elements (e.g., cost center, cost element) that is necessary for the transaction you are trying to execute.
  Incorrect Configuration: There may be issues with the configuration of the controlling area, cost centers, or cost elements that prevent the system from recognizing valid combinations.
