• What is the cause and solution for SAP error message MM_PUR_SES060 - A service entry sheet with the same ext. reference already exists: &1, &2 ?

  The SAP error message MM_PUR_SES060 indicates that you are trying to create a service entry sheet (SES) that has the same external reference as an existing one. This is a validation check to prevent duplicate entries for service entry sheets, which can lead to inconsistencies in procurement and accounting processes.
  Cause:
  The error occurs when:
  
  You attempt to create a new service entry sheet with an external reference (like a purchase order number or a reference number) that already exists in the system.
  The external reference is meant to be unique for each service entry sheet, and the system is enforcing this uniqueness.
  
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Check Existing Service Entry Sheets:
  
  Use transaction code ML81N (Service Entry Sheet) to view existing service entry sheets.

  Modify Existing Entry:
  
  If the existing service entry sheet is incorrect or needs to be updated, you can modify it instead of creating a new one.
  
  
  
  Use a Different External Reference:
  
  If the existing service entry sheet is valid and should remain unchanged, consider using a different external reference for your new service entry sheet.
  
  
  
  Consult Documentation:
  
  Review any relevant documentation or guidelines within your organization regarding the use of external references in service entry sheets.
  
  
  
  Check for System Customizations:
