• What is the cause and solution for SAP error message OH080 - Group is not unique (incorrect intervals or overlaps) ?

  The SAP error message OH080 ("Group is not unique (incorrect intervals or overlaps)") typically occurs in the context of defining or managing work schedules, particularly when dealing with time management or personnel planning in SAP. This error indicates that there are overlapping or non-unique intervals defined for a specific grouping of time-related data, such as work schedules, absence types, or other time-related configurations.
  Causes:
  
  Overlapping Time Intervals: Two or more time intervals defined for the same group overlap, which means that the system cannot determine which interval to apply.
  Non-Unique Entries: There are multiple entries for the same time period or group that are not distinct, leading to ambiguity.
  Incorrect Configuration: The configuration of time management settings may not adhere to the required rules, leading to conflicts in the defined intervals.
  Data Entry Errors: Manual entry errors when defining time intervals can lead to overlaps or duplicates.
  
  Solutions:
  
  Review Time Intervals: Check the time intervals defined for the group in question. Ensure that there are no overlaps or duplicate entries. Each interval should be distinct and non-overlapping.
  Adjust Configuration: If you find overlapping intervals, adjust the start and end times to ensure they do not conflict. Make sure that each entry is unique.
  Use the SAP Transaction Codes: Utilize relevant transaction codes (like PA30 for personnel administration or PT60 for time evaluation) to review and modify the time data.
  Check for Related Entries: Sometimes, the issue may arise from related entries in other configurations (like absence types or work schedules). Ensure that all related entries are consistent and do not conflict.
  Consult Documentation: Refer to SAP documentation or help resources for specific guidelines on configuring time management settings to avoid such errors.
  Testing: After making changes, test the configuration to ensure that the error does not reoccur and that the system behaves as expected.
