• What is the cause and solution for SAP error message KZ159 - Cost object & does not allow assignment of single objects ?

  The SAP error message KZ159 indicates that a cost object (such as a cost center, internal order, or project) does not allow the assignment of single objects. This typically occurs in the context of cost accounting when trying to assign costs or transactions to a cost object that is not configured to accept such assignments.
  Cause:
  
  Cost Object Configuration: The cost object may not be set up to allow the assignment of single objects. For example, certain cost centers or internal orders may be configured to only accept aggregated costs or may have restrictions based on their status.
  Transaction Type: The type of transaction you are trying to post may not be compatible with the cost object. For instance, some transactions may require a specific type of cost object that allows for single assignments.
  Authorization Issues: There may be authorization restrictions preventing the assignment of costs to the specified cost object.
  Status of Cost Object: The cost object may be inactive or closed, which would prevent any further assignments.
  
  Solution:
  
  Check Cost Object Configuration: Review the configuration of the cost object in the SAP system. Ensure that it is set up to allow the assignment of single objects. This can be done in the controlling (CO) module settings.
  Review Transaction Type: Ensure that the transaction you are trying to post is compatible with the cost object. If necessary, change the transaction type or use a different cost object that allows single assignments.

  Consult Documentation: Refer to SAP documentation or consult with your SAP support team for specific configuration settings related to the cost object in question.
