• What is the cause and solution for SAP error message KS091 - Statistical cost center already exists ?

  The SAP error message KS091, which states "Statistical cost center already exists," typically occurs when you attempt to create a statistical cost center in SAP that has the same identifier as an existing one. This can happen during the creation of a new cost center in the Controlling (CO) module.
  Cause:
  
  Duplicate Identifier: The primary cause of this error is that the cost center you are trying to create already exists in the system with the same identifier (cost center code).
  Incorrect Data Entry: There may have been a mistake in entering the cost center code, leading to an attempt to create a duplicate.
  System Configuration: In some cases, the system configuration may allow for the creation of statistical cost centers, but the existing cost center is not being recognized due to data inconsistencies.
  
  Solution:
  
  
  Check Existing Cost Centers: 
  
  Use transaction code KS03 (Display Cost Center) to check if the cost center you are trying to create already exists. If it does, you may need to use that existing cost center instead of creating a new one.
  
  
  
  Use a Different Identifier: 
  
  If you need to create a new statistical cost center, ensure that you are using a unique identifier that does not conflict with existing cost centers.
  
  
  
  Review Data Entry: 
  
  Double-check the data you are entering for any typos or errors in the cost center code.
  
  
  
  Consult with Your SAP Administrator: 
  
  If you believe that the cost center should not exist or if there are issues with the system configuration, consult with your SAP administrator or support team for further investigation.
  
  
  
  Check for Deactivated Cost Centers: 
  
  Sometimes, a cost center may be deactivated but still exists in the system. You can check if the cost center is inactive and decide whether to reactivate it or create a new one.
  
  
  
  Related Information:
  
  Cost Center Types: Understand the difference between statistical and primary cost centers. Statistical cost centers are used for tracking purposes and do not affect financial postings.
  Transaction Codes: Familiarize yourself with relevant transaction codes such as:
  
  KS01: Create Cost Center

  KS03: Display Cost Center
  
  
  SAP Documentation: Refer to SAP Help documentation for detailed information on cost center accounting and error messages.
