• What is the cause and solution for SAP error message KE0C005 - A source cost element has already been defined for assignment & ?

  The SAP error message KE0C005 indicates that there is an issue with the assignment of a source cost element in the Controlling (CO) module. Specifically, it means that a source cost element has already been defined for the assignment you are trying to make, which prevents you from creating a duplicate assignment.
  Cause:
  The error typically arises in the following scenarios:
  
  Duplicate Assignment: You are attempting to assign a cost element to a cost center, internal order, or another object that already has that cost element assigned.
  Configuration Issues: There may be a configuration issue in the Controlling module where the same cost element is being used in multiple places incorrectly.
  Data Entry Error: There might be a mistake in the data entry process where the same cost element is being entered multiple times.
  
  Solution:
  To resolve the KE0C005 error, you can take the following steps:
  
  
  Check Existing Assignments:
  
  Go to the relevant transaction (e.g., KE51 for cost centers, KO01 for internal orders) and check if the cost element is already assigned to the object you are trying to assign it to.
  If it is already assigned, you may need to modify or remove the existing assignment before making a new one.
  
  
  
  Review Configuration:
  
  If you suspect a configuration issue, review the settings in the Controlling module to ensure that cost elements are set up correctly and that there are no conflicting assignments.
  
  
  
  Use Different Cost Element:
  
  If the cost element is indeed already in use and you need to make a new assignment, consider using a different cost element that is not currently assigned.
