• What is the cause and solution for SAP error message 5M121 - A payroll run already exists with the same key dates ?

  The SAP error message 5M121 indicates that a payroll run already exists for the specified key dates. This typically occurs when you attempt to execute a payroll run for a period that has already been processed, or when there is an attempt to create a duplicate payroll run for the same employee and period.
  Cause:
  
  Duplicate Payroll Run: The most common cause is that a payroll run has already been executed for the same employee and period.
  Incorrect Key Dates: The key dates (such as the payroll period start and end dates) you are trying to use may overlap with an existing payroll run.
  System Configuration: There may be issues with the configuration of the payroll schema or the way payroll runs are being processed in the system.
  
  Solution:
  
  
  Check Existing Payroll Runs: 
  
  Use transaction code PC00_MXX_CALC (where MXX is your country-specific payroll driver) to check if a payroll run has already been executed for the specified period.
  You can also use transaction PA03 to view the payroll results for the employee in question.
  
  
  
  Review Key Dates: 
  
  Ensure that the key dates you are using for the payroll run do not overlap with any existing payroll runs. Adjust the dates if necessary.
  
  
  
  Delete or Adjust Existing Payroll Run: 
  
  If you find that a payroll run has been executed but needs to be adjusted, you may need to reverse or delete the existing payroll run. This can be done using transaction PC00_MXX_CEDT (for correction) or PC00_MXX_CEED (for deletion), depending on your requirements.
  
  
  
  Consult with Payroll Administrator: 
  
  If you are unsure about the implications of deleting or adjusting payroll runs, consult with your payroll administrator or SAP support team to ensure compliance with your organization's payroll policies.
  
  
  
  Check for System Errors: 
  
  If you believe this error is occurring incorrectly, check for any system errors or inconsistencies in the payroll configuration that may need to be addressed.
  
  
  
  Related Information:
  
  Transaction Codes: Familiarize yourself with relevant transaction codes such as PA03, PC00_MXX_CALC, PC00_MXX_CEDT, and PC00_MXX_CEED for managing payroll runs.
