How To Fix SABP_KEY_REDUNDANCY026 - The keys &1 and &2 are unique

SAP Error Message - Details

• Message type: E = Error

• Message class: SABP_KEY_REDUNDANCY - Superfluous Keys Messages

• Message number: 026

• Message text: The keys &1 and &2 are unique

What causes this issue?

The table keys &V1& and &V2& are unique and the components of &V2& are
an initial part (SORTED) or a subset (HASHED) of &V1&.
Check whether &V1& can be removed.
INCLUDE INCL_MIGRATION_SCENARIO
Since both keys have the same access semantics but key &V2& has fewer
components, access with &V2& provides better performance. Check whether
the redundant keys were created in a migration scenario and whether one
of the two keys can be removed.

The message specifies that the keys &1 and &2 are unique, meaning that the system has detected that the values for these keys are not unique and are causing a conflict.

  Incorrect Data Input: The data being inputted may not be validated properly, leading to attempts to create duplicate records.
  Configuration Issues: There may be issues with the configuration of the database or the application logic that is supposed to enforce uniqueness.
  
  Solution:
  
  Check Existing Records: Review the existing records in the database to identify if the keys you are trying to use already exist. You can do this by querying the relevant table.
  Modify Input Data: If you find that the keys are indeed duplicates, you will need to modify the input data to ensure that the keys are unique before attempting to insert or update the record again.
  Data Validation: Implement or enhance data validation checks in your application to prevent duplicate entries from being submitted in the first place.
  Consult Documentation: Review the relevant SAP documentation or consult with your SAP administrator to understand the specific context of the keys involved and any additional constraints that may be in place.
  Debugging: If you are a developer, you may want to debug the code that is generating this error to understand the flow of data and where the duplication is occurring.
