  The SAP error message /PRA/CHECK_INPUT174 Duplicate record for sequence number &1 typically occurs in the context of the SAP Payroll or Personnel Administration modules, particularly when dealing with infotypes or records that require unique sequence numbers. This error indicates that there are multiple entries with the same sequence number for a specific infotype, which violates the uniqueness constraint expected by the system.
  Cause:
  
  Duplicate Entries: The most common cause of this error is that there are duplicate records in the database for a specific infotype with the same sequence number. This can happen due to incorrect data entry, data migration issues, or system errors.
  Data Uploads: If data is being uploaded into the system (e.g., through LSMW or other data migration tools), and the sequence numbers are not properly managed, duplicates can occur.
  Concurrent Processing: If multiple processes are trying to create or update records simultaneously, it may lead to duplicate entries.
  
  Solution:
  
  Identify Duplicates: Use transaction codes like SE16 or SE11 to query the relevant infotype table (e.g., PA0001 for infotype 0001) and check for duplicate entries with the same sequence number.
  Remove Duplicates: Once identified, you can either delete the duplicate records or correct them to ensure that each sequence number is unique. Be cautious when deleting records to avoid losing important data.
  Data Validation: Implement validation checks in your data entry processes to prevent duplicates from being created in the first place.
  Review Data Upload Processes: If the error arises during data uploads, review the upload logic to ensure that sequence numbers are generated correctly and that duplicates are avoided.
  Consult Documentation: Check SAP notes or documentation related to the specific infotype you are working with for any known issues or additional guidance.
