• What is the cause and solution for SAP error message SS124 - Primary assignment for activity & already exists ?

  The SAP error message SS124 ("Primary assignment for activity & already exists") typically occurs when there is an attempt to assign a primary activity to a cost center, internal order, or another object that already has a primary assignment for that activity. This can happen in various SAP modules, particularly in Controlling (CO) or Project System (PS).
  Cause:
  
  Duplicate Assignment: The primary activity you are trying to assign is already assigned to the same object. In SAP, each activity can only have one primary assignment to avoid confusion in cost allocation.
  Configuration Issues: There may be issues in the configuration of the activity types or the cost centers that lead to this error.
  Data Integrity Issues: There might be inconsistencies in the master data or transactional data that are causing the system to recognize a duplicate assignment.
  
  Solution:
  
  
  Check Existing Assignments: 
  
  Go to the relevant transaction (e.g., KP26 for activity type planning) and check if the activity is already assigned to the cost center or internal order.
  If it is, you may need to remove the existing assignment before making a new one.
  
  
  
  Review Configuration:
  
  Ensure that the configuration for activity types and cost centers is set up correctly. You can check this in the SPRO transaction under the Controlling section.
  Verify that the activity type is not mistakenly assigned to multiple cost centers as a primary assignment.
  
  
  
  Data Cleanup:
  
  If there are inconsistencies in the data, you may need to clean up the master data. This could involve deleting or correcting erroneous entries.
  
  
  
  Consult Documentation:
  
  Review SAP documentation or help files related to activity assignments for further insights on how to manage assignments correctly.
