• Message number: 020

• Message text: Refer to the long text for more information

What causes this issue?

The table key &V1& is unique and &V2& is not unique. However, the
components of &V1& are a subset of &V2&, which means that &V1& is more
selective than &V2&.
INCLUDE INCL_MIGRATION_SCENARIO
Check whether both keys are really needed or if one of the keys can be
removed.
The message is also issued if &V2& is a generic primary key whose
uniqueness is unknown. In this case, the worst case scenario is assumed
(that the primary key is not unique). However, since the unique
secondary key is a subset of the primary key at the same time, the
primary key must be unique. Check the definition of the primary key and
define it as unique if appropriate.

• What is the cause and solution for SAP error message SABP_KEY_REDUNDANCY020 - Refer to the long text for more information ?

  The SAP error message SABP_KEY_REDUNDANCY020 typically indicates that there is a redundancy in the key fields of a certain data structure, such as a master data record or a transaction record. This error often arises when you are trying to create or update records in a table where the key fields must be unique, and the system has detected that the values you are trying to enter already exist in the database.
  Cause:
  
  Duplicate Key Values: The most common cause of this error is that the key values you are trying to enter already exist in the database. This can happen if you are trying to create a new record with the same key as an existing record.
  Data Migration Issues: If you are migrating data from another system or performing bulk uploads, there may be duplicates in the data being imported.
  Incorrect Configuration: Sometimes, the configuration of the data model or the way the keys are defined can lead to this error.
  
  Solution:
  
  Check Existing Records: Before creating or updating a record, check the existing records in the database to ensure that the key values you are trying to use are not already in use.
  Modify Key Values: If you find that the key values are indeed duplicates, you will need to modify the values you are trying to enter to ensure they are unique.
  Data Cleansing: If you are migrating data, perform a data cleansing process to remove duplicates before the migration.
  Review Configuration: If the issue persists, review the configuration of the data model to ensure that the key fields are correctly defined and that there are no unintended constraints causing the redundancy.
