  The SAP error message 5G220, which states "Record already exists in the table NI Data Take-on (T5G_DTONI)," typically occurs during the data take-on process in the SAP system, particularly when dealing with the NI (National Insurance) data for employees. This error indicates that there is an attempt to insert a record into the T5G_DTONI table that already exists, which violates the uniqueness constraint of the table.
  Cause:
  
  Duplicate Entry: The most common cause of this error is that the record you are trying to insert already exists in the T5G_DTONI table. This could happen if the data was previously uploaded or entered manually.
  Incorrect Data Load: If you are using a data upload tool or program, it may be configured incorrectly, leading to duplicate entries being attempted.
  Data Migration Issues: During data migration from another system, if the same records are being migrated multiple times, this error can occur.
  
  Solution:
  
  Check Existing Records: Before attempting to insert a new record, check the T5G_DTONI table to see if the record already exists. You can do this using transaction SE11 (Data Dictionary) or SE16 (Data Browser).
  Modify the Data Load: If you are using a data load program, ensure that it is set up to check for existing records before attempting to insert new ones. This may involve adding logic to skip records that already exist.
  Delete or Update Existing Records: If the existing record is incorrect or needs to be updated, you can either delete the existing record (if appropriate) or update it with the new information instead of trying to insert a new one.
  Consult Documentation: Review any relevant SAP documentation or notes related to the NI Data Take-on process to ensure compliance with the expected data structure and constraints.
