  The SAP error message SABP_KEY_REDUNDANCY021 indicates that there is a redundancy in the unique keys being used in a particular context, such as when trying to create or update a record in a database table. The message specifies that the keys &1 and &2 are unique, meaning that the system has detected that the combination of these keys already exists in the database, which violates the uniqueness constraint.
  Cause:
  
  Duplicate Entries: The most common cause of this error is that you are trying to insert or update a record that would result in duplicate values for fields that are defined as unique keys in the database.
  Data Entry Errors: There may be a mistake in the data being entered, leading to an attempt to create a record that conflicts with existing records.
  Incorrect Logic in Custom Code: If there is custom code (like ABAP programs or enhancements) that manipulates data, it may not be handling unique constraints properly.
  
  Solution:
  
  Check Existing Records: Review the existing records in the database table to see if the combination of keys &1 and &2 already exists. You can use transaction codes like SE16 or SE11 to view the table data.
  Modify Input Data: If you find that the keys already exist, you will need to modify the input data to ensure that it does not conflict with existing records. This may involve changing one of the key values or ensuring that the record you are trying to create is unique.
  Review Custom Code: If the error is occurring in a custom program, review the logic to ensure that it correctly checks for existing records before attempting to insert or update.
  Consult Documentation: Check the SAP documentation or help resources for the specific transaction or module you are working with to understand the unique key constraints better.
