• What is the cause and solution for SAP error message SGT_01302 - A combination with the same start/end date already exists or overlaps ?

  The SAP error message SGT_01302 indicates that there is an issue with date combinations in the system. Specifically, it means that the system has detected that a combination of start and end dates you are trying to enter already exists or overlaps with an existing entry. This error is commonly encountered in modules that deal with time periods, such as SAP SuccessFactors, SAP S/4HANA, or other SAP applications that manage data with date ranges.
  Cause:
  
  Duplicate Entries: You are trying to create a new entry that has the same start and end dates as an existing entry.
  Overlapping Dates: The new entry's date range overlaps with an existing entry's date range. For example, if you have an existing entry from January 1 to January 10, and you try to create a new entry from January 5 to January 15, this will trigger the error.
  Data Integrity Rules: The system has built-in rules to maintain data integrity, preventing overlapping or duplicate date ranges.
  
  Solution:
  
  Check Existing Entries: Review the existing entries in the relevant table or module to identify any overlaps or duplicates. You can do this by querying the database or using the relevant transaction codes in SAP.
  Adjust Dates: Modify the start and/or end dates of the new entry to ensure that they do not overlap with existing entries. Make sure that the new date range is unique.
  Delete or Modify Existing Entries: If the existing entry is no longer needed, consider deleting or modifying it to accommodate the new entry.
  Consult Documentation: Refer to the specific SAP module documentation for guidelines on how to manage date ranges and understand the rules governing them.
  Contact Support: If you are unable to resolve the issue, consider reaching out to your SAP support team or consulting SAP Notes for any known issues or patches related to this error.
  
  Related Information:
  
  Transaction Codes: Depending on the module, you may use specific transaction codes to view or manage entries (e.g., SE16 for table views, or specific transaction codes for HR or project management).
  SAP Notes: Check SAP Notes for any updates or patches that may address this issue.
  User Permissions: Ensure that you have the necessary permissions to create or modify entries in the system, as restrictions may also lead to errors.
  Testing: If you are in a development or testing environment, try replicating the issue with different date combinations to better understand the constraints.
  
  By following these steps, you should be able to identify the cause of the error and implement a solution to resolve it.
