• What is the cause and solution for SAP error message KP581 - Enter only one CO object ?

  The SAP error message KP581 ("Enter only one CO object") typically occurs in the context of controlling (CO) module transactions, particularly when you are trying to enter data related to cost centers, internal orders, or other CO objects. This error indicates that the system expects you to specify only one CO object, but it has detected multiple entries or an incorrect format.
  Cause:
  
  Multiple CO Objects: You may have inadvertently entered multiple cost centers, internal orders, or other CO objects in a field that only allows a single entry.
  Incorrect Input Format: The input might not conform to the expected format, leading the system to misinterpret the entry as multiple objects.
  Configuration Issues: There may be configuration settings in the controlling area that are causing the system to expect a single CO object.
  
  Solution:
  
  Check Input Fields: Review the fields where you are entering CO objects. Ensure that you are only entering one valid CO object. If you need to enter multiple objects, check if there is a different way to do so (e.g., using a different transaction or report).
  Correct Format: Make sure that the CO object is entered in the correct format. For example, if you are entering a cost center, ensure that it is a valid cost center code.
  Review Transaction Settings: If you are using a specific transaction, check the documentation or help files to understand the expected input. Some transactions may have specific requirements for CO object entries.
  Consult Configuration: If you suspect a configuration issue, consult with your SAP administrator or a functional consultant to review the settings in the controlling area.
